I need to unlock my BIOS to show some hidden options (Such as undervolt protection, etc.)
It’s there but its hidden (looked this up in SetupUtility from BIOS dump through IFRExtract)
OneOf Prompt: “UnderVolt Protection”, Help: “When UnderVolt Protection is enabled, user will not be able to program under voltage in OS runtime. Recommended to keep it enabled by default. Enabled: Allow BIOS undervolting, but enable UnderVolt Protection in Runtime. Disabled: No UnderVolt Protection in Runtime.”, QuestionFlags: 0x10, QuestionId: 0x2F0, VarStoreId: 0x3, VarOffset: 0x381, Flags: 0x10, Size: 8, Min: 0x0, Max: 0x1, Step: 0x0
OneOfOption Option: “Disabled” Value: 0
OneOfOption Option: “Enabled” Value: 1, Default, MfgDefault
End
End

If you need the dump, ask for it (im not sure if I did it right because im not able to find my BIOS on motherboard, lol)

you’ll have to check first the Intel Boot Guard Measured and Verified Boot FPF value then try flash your own dump (not stock bios) again in FPT as well disabled BIOS Lock and FPRR setting with Grub mod.
