You cannot install Windows 11 with Legacy BIOS. Installing in Legacy or CSM mode on a modern UEFI BIOS is like buying a new car and disabling all of the safety and performance features.
So you'd either need to reinstall Windows 10 exactly as I wrote out with illustrated tutorials, install Windows 11 in UEFI mode which I again gave you illustrated tutorials showing how to do this, or if you want to try to convert your present install to UEFI you can try this method:

Once you convert the install and enable UEFI mode in BIOS, hopefully Secure boot will be apparent in the BIOS settings.
If not, then again I told you every single step you should make, even provided your BIOS Manual, the latest BIOS Update, how to contact Asus Support or a dozen different Asus forums that can help you with the specific settings in your Asus BIOS, since they are all different.
There is no one else on the web who would have taken the time and effort to do all of this research for you, posted back step by step instructions, each step illustrated by a tutorial explaining how to do it.
So trying to upgrade to windows 11. I had the error of no TPM 2.0 and secure boot disabled. So I went into the bios and got the TPM error to go away and also enabled secure boot. I had to disable the CSM to enable the secure boot but it wouldn’t boot windows with the CSM disabled so I turned it back on and was able to boot up fine.
The issue is that I am still getting the error that secure boot is the reason I can’t download windows 11. When I go to info I see secure boot state as unsupported. Not sure what to do from here. Not sure if the CSM being enabled is messing this up.
Secure Boot Enabled in BIOS, but not Windows 11
Unsupported secure boot state
[Solution] Secure Boot Disabled
secure boot state unsupported

Hi Alireza. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.
There's a November 2021 BIOS Update here if yours is not updated:
https://www.asus.com/Motherboards-Components/Mo...
Then you can read the Manual here to find out how to enable Secure Boot:
https://www.asus.com/Motherboards-Components/Mo...
If it's still not clear then contact Asus Support to find out how to enable Secure Boot on your BIOS:
https://www.asus.com/support/
You can also ask in Asus forums:

Is Windows presently installed in UEFI mode, as this can make a big difference in Secure Boot showing up? If you're unsure type System Information in Search, open and look for BIOS mode.
If not installed to UEFI I'd consider reinstalling to UEFI either with WIndows 10 doing this gold standard Clean Install which includes everything that works best in Windows 10: http://answers.microsoft.com/en-us/windows/wiki...
or do a Windows 11 Clean Install:

Make sure to create the bootable media using Media Creation Tool only, boot the media as a UEFI device, delete all partitions down to Unallocated Space to clear formatting, then select the Unallocated Space and click Next to let the installer create and format the needed partitions - which makes it foolproof.
Feel free to ask back any questions. If you'll report back results for each step it can help determine what else needs to be tried. I will stick with you until it is fixed.

I had the same problem on a Lenovo ThinkPad P52.
In the BIOS, Secure Boot was enabled, but Windows 11 showed "Secure Boot State" as "Off".
The cause was, that the Secure Boot Mode in my BIOS was set to "Setup Mode".
To change it to "User Mode", I had to select "Restore Factory Keys" on the Security Page in the BIOS.
After that, I could start the computer and Windows 11 displayed that the Secure Boot State is "On".
Maybe this helps someone.
I’ve been searching for hours, I finally can play valorant again lol. Thank you!!
So I’m trying to upgrade to windows 11 and it saying that secure boot isn’t supported but I turned it on in my bios but it still didn’t fit the issue. I’ve tried looking online and watching videos and found that I need to change my boot drive from MBR to GPT but it’s not letting me and I don’t know if it’s because my disk 0 is dynamic or if that even matters, I just need help because this is really annoying me and I don’t know what to do.
I haven’t seen this solution posted before.
The answer to the “secure boot is disabled” is actually as simple as enabling secure boot. However if you just enabled it through BIOS, are on windows 11 and do not have a brand new motherboard model then windows will not allow you to enable secure boot even though it says enabled on the BIOS.
I followed the instructions from the website below ————————————————————— CHECK SECURE BOOT:
-
Press Windows image + R keys to open the run command box.
-
Type msinfo32 and click OK to open System Information.
-
On the System Information page, check the BIOS Mode and the Secure Boot Status.
If BIOS mode is set to: UEFI Secure Boot status set to: Off
proceed to the steps below ———————————————-
Part 1. Enable Secure Boot in BIOS/UEFI. Activate Secure Boot in UEFI Firmware settings from Windows RE.
-
Hold down the Shift key and from the Power icon image select Restart to boot your system in Windows Recovery Environment (WinRE).
-
Then select Troubleshoot -> Advanced options -> UEFI Firmware Settings and select Restart.
-
Navigate to the System Configuration tab, select Boot Options.
-
In Boot options, Change Secure Boot and select Enabled.
-
Save and Exit from BIOS Settings.
and while a bit technical it should end up working. https://www.wintips.org/fix-secure-boot-unsupported-or-unavailable/
