This happened to me on my ASUS board. I had to enable CSM first, then the Secure Boot option finally showed up. Hope that helps.

I had the same problem. After enabling CSM, I also had to switch it from "Legacy" to "UEFI" mode before Secure Boot became available. Good luck!

Yeah, You could also try updating your BIOS to the latest version from ASUS's website, as that sometimes adds the Secure Boot option.

Same here. Agreed, updating the BIOS often unlocks it. Just make sure to enable the "TPM" or "Trusted Platform Module" setting in there too, as Windows 11 needs both.

This. You could also check for a setting called "Windows 8/10 Features" or something similar in the BIOS, as that sometimes controls Secure Boot on older boards. Good luck!

Also, make sure your BIOS is set to UEFI mode, not Legacy/CSM, as Secure Boot requires that.
