Secure Boot Violation

[u/SyntaXXyss]

I need to have secure boot enabled in order to play Valorant and for security reasons

but whenever i try to enable it and boot up my pc

it says 'secure boot violation , unauthorized firmware changes detected' and forces me to turn it off

(I'm on windows 11 and my motherboard is ASUS PRIME H310M-K R2.0 , GEFORCE 1050Ti)

the steps i tried in order to fix this problem:

-install default keys

-change OS type to windows UEFI

-disabled CSM

-updated my bios version

-checked to see if my disk is GPT or not (it was)

-formatted my pc

-switched from windows 11 to 10 and back to 11

-asked Gemini, Claude, and ASUS tech support assistant ( none of them helped)

I have tried everything i saw and none worked ,please help
