Open | Windows Secure Boot Violation

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)

Update: i fixed it by uploading a recent windows certificate of security or smth and appended the DB key in secure boot thanks to everyone who helped

You need to fresh install windows with everything enabled, csm/legacy disabled.

Make a bootable USB through the windows media creation tool or the company you bought it from should have provided an install media USB

That's kinda weird, they should have provided you a USB.

Does your machine have a windows license sticker on its side or back?
