You could also try updating your motherboard's BIOS to a newer version, as that often adds the Secure Boot option.

Same here. Sometimes you also need to switch the boot mode from Legacy to UEFI before Secure Boot becomes available.

+1 You could also check if there's a BIOS update for your specific ASUS board, as that sometimes adds the Secure Boot option. Hope that helps.

Agreed. Also, look for a setting called "Launch CSM" and make sure it's disabled, as that can hide the Secure Boot option. Hope that helps.
