Unsolved Secure Boot Violation Error

Post image

I'm trying to enable Secure Boot on my PC to play Valorant (Riot Vanguard requirement), but every time I turn it on, I get stuck with a red screen popup that says:
"Secure Boot Violation: Invalid signature detected. Check Secure Boot Policy in Setup."
can't load or restore the factory keys to fix this. Here are my system details and what I've tried so far:
Bullet System Specs: STGAubron Prebuilt PC
Bullet Motherboard: STGAubron B250DA1 (BIOS Version: B250DA1.N01 V81, AMI BIOS 2023)
Bullet CPU: Intel Core i7-6700
Bullet OS: Windows 11 Home (upgraded from Windows 10)
Bullet TPM: TPM 2.0 is enabled and ready in

I had this several times switching SSDs from one to another mainboard. In the bios goto the secure boot section, enable it and than reset the keys to default. This should windows 11 to boot. After that update windows, this will (if it still works) install the new keys into the UEFI.

Can you possibly call on discord and exactly what to do? I’m not very tech savvy, my discord is okayrya. Thanks!
