How do I enable secure boot for the asus z690 hero?

[aliasgoob]

Can’t find a way to enable secure boot on my z690. Even after searching the web, nothing appears to tell me how to enable secure boot on my z690, even if I follow steps with similar motherboards.

Put your BIOS into Advanced Mode.  Click the Boot tab.

Doesn't work. Properly configuring all my settings to enable secure boot still leads to my msinfo32 to show my secure boot as "unsupported".

After opening the Boot tab, did you then click the Secure Boot entry, then enable it?
