I'm going to assume that your laptop was set up for legacy boot (for some reason) and you switched it to UEFI, since Secure Boot requires UEFI. That being the case from BIOS go to the BOOT menu, set BOOT MODE to LEGACY SUPPORT, and set BOOT PRIORITY to LEGACY FIRST. Exit while saving changes and it should boot into non-UEFI (legacy) mode.

Can't disable Secure Boot on T470
What you discribe means that the Bios is password protected on newer Thinkpads. If you can't find someone who knows the password you have quite a problem as you can't remove it in newer models as the T430 series as far as I remember. You can also make the bootable USB drive secure boot compatible in some cases, so you can atleast use the laptops when you can't return it. Edit: Just forget my last sentence. That won't work for Manjaro. (Correct me if I'm wrong and you find a solution) More on reddit.com

r/thinkpad on Reddit: Can't disable Secure Boot on T470
November 15, 2021 -
I want to disable Secure Boot in order to boot from USB on a used T470 I just bought. I can enter the BIOS (it asks for a password, but just hitting enter goes through, which indicates the BIOS isn't locked, right?) but once I'm in, although I can navigate to all tabs and sub-items, it doesn't let me select any value to actually change it.
I have successfully booted both Ubuntu and Mint ISOs, since they are signed for Secure Boot. But my distro of choice is Manjaro.
Did I bought a device that is locked somehow, or I'm missing something really obvious? I'm new to this Secure Boot / BIOS thing (have been using Linux for a few years on old Macs...), and have read some accounts of people bricking their devices messing with this, so I want to be cautious.
Thanks for any help.
EDIT: CompuTrace tab reads: Current Setting - [Enable] / Current State - Not Activated

Did I bought a device that is locked somehow Yes, it's locked. You need a password or you need a significantly complicated (and costly) process to reset it. Can you send the laptop back?

You need to enable Secure Boot then look for Restore Factory Keys setting (also in the BIOS). Don't use it if you're using Bitlocker as that can cause your system to be unbootable.

After these databases have been added, and after final firmware validation and testing, IBM locks the firmware from editing, except for updates that are signed with the correct key or updates by a physically present user who is using firmware menus, and then generates a PK. The PK can be used to sign updates to the KEK or to turn off Secure Boot.
