You might be in Setup Mode because you have deleted the Platform Key in your BIOS. Enabling Secure Boot in this state enables your OS to write a new Platform Key (possibly useful for securing a Linux installation). But if you don't do that, you remain in Setup Mode and the Secure Boot State, indicating the Platform Key has been used to secure the system, will remain off.
Your BIOS might have an option to restore the default Platform Key, possibly called "Restore Default Secure Boot Keys", which restores the Microsoft Key. After doing that, your Secure Boot State will be On when booting Windows.

October 24, 2019No Secure Boot Option
I have a B450 Tomahawk. Made sure my drive that boots up my Windows (SSD in my case ) had a partition style: GPT and not MBR. Then, in BIOS, I had to set it from Legacy/UEFI to UEFI, saved then restarted. Went back into BIOS and I found the CSM to UEFI switch in the Advanced Tab / Windows OS configuration / BIOS CSM/UEFI and changed it, and for me, I already saw the Secure Boot option ON but chose to disable it like you mentioned for the reboot. After it restarted like normal, I ONCE more went back into BIOS and enabled Secure Boot. Probably rebooted more than I needed to but it worked! Such a headache. More on reddit.com

On systems that old, the option for Secure Boot is hidden and the motherboard needs CSM disabled in order for it to appear ... First, you need to make sure your Windows drive is in GPT instead of MBR because it won't boot after disabling CSM unless it's converted to GPT. There's plenty of tutorials on YouTube on how to convert your Windows drive without losing data ... After the conversion, boot into the BIOS and look for a setting called "Windows 8/10 WHQL Support" and enable it. This option is actually a toggle switch between CSM and UEFI Mode, and once it's enabled, the motherboard will disable CSM, enable UEFI Mode. So enable it first, save and exit, and confirm that Windows 10 boots afterwards. It should because of the drive conversion. From here, return to the BIOS and the Secure Boot section should now be revealed. Chose to enroll the platform keys and let it reboot .... then cross your fingers. There's a 50/50 chance that enrolling the platform keys will corrupt your BIOS and brick your motherboard ... You also need a GPU manufactured around 2019 to ensure it has a UEFI compliant VBIOS ...

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.

UEFI/GPT has been the standard for a decade. UEFI supports larger drives, boots faster because UEFI runs in 32/64-bit mode rather than 16-bit mode, handles initializing multiple hardware devices during boot better than BIOS/MBR, and supports modern hardware better than BIOS/MBR in general. Unless you have an ancient computer, it is almost certainly UEFI/GPT OTB. I can't think of a reason to use BIOS/MBR if your computer supports UEFI/GPT.

First thoughts, I may be mistaken on some of the below... I have heard UEFI can boot faster. (no idea how/why), or that may be with use of systemd-boot instead of grub it can be a bit faster. UEFI can use rEFInd which is a nicer looking boot menu with some nice features. Legacy/MBR setup may require the disk to have the MBR/DOS partition table standard which has limits compared to GPT which can be used with uefi I think ,it's possible to use uefi with the old MBR/Dos partition table , and I thought it was possible to do a legacy setup with GPT, but I have heard that can be problematic. UEFI has been around for years now, and is not going away, and is a mature standard. I have heard some systems/motherboards are removing the legacy/MBR/bios stuff. (no idea where I read that) I can't really see any reason to stick to the old MBR except if you have legacy hardware, or for some reason don't want to use an EFI partition. Just my take on it. have fun.
