I upgraded to Windows 11 and needed to switch my Gigabyte motherboard to UEFI mode for certain games. I disabled CSM Support and enabled Secure Boot, then saved and restarted as instructed. However, I can no longer reach the BIOS to complete the next step: restoring the Secure Boot factory keys and enabling Secure Boot again.
I have already tried disabling Windows Fast Startup, using Shift while selecting Restart, running `shutdown /r /fw` from an administrator Command Prompt and PowerShell, and repeatedly pressing Delete during startup. Each time, the computer boots directly into Windows instead of opening the firmware settings. What else can I try to access the BIOS?

Try the correct firmware key for your exact Gigabyte motherboard. Delete is common, but some systems use F2 or another key. You can also press the boot-menu key, often F12, because it may include an option to enter BIOS setup.
From Windows, open Settings, go to System > Recovery, choose Advanced startup, and restart. Then select Troubleshoot > Advanced options > UEFI Firmware Settings. If that option appears, use it to reboot directly into the firmware setup screen.
If the normal keys and Windows recovery option do not work, check the motherboard manual for its BIOS recovery or Q-Flash feature. Reflashing should be a last resort: identify the exact motherboard revision and compatible BIOS version first, and use a correctly prepared USB drive. Do not interrupt power during the update.
