Need Help: Secure Boot / CSM / Boot Issue (Gigabyte BIOS)
Hi everyone, I need help with a BIOS/boot issue I’ve been stuck on.
I’m using a Gigabyte motherboard (Z790 AERO G).

Main problem:
I was trying to enable Secure Boot
After changes, I got a “Secure Boot Violation / Invalid Signature Detected”
I disabled Secure Boot to recover, but now I have more issues

Current issues:
Secure Boot option is GRAYED OUT
CSM Support cannot be enabled (it turns off automatically after reboot)
I already tried:
Clearing CMOS (removed battery)
Using BIOS admin/supervisor password
Using Secure Boot key management / variables reset
None of these fixed it
