How do I turn secure boot off in UEFI BIOS on an ASUS TUF Gaming board?

Question

I've tried following various tutorials. The closest one to displaying similar screens as I have was this: https://www.technorms.com/45538/disable-enable-secure-boot-asus-motherboard-uefi-bios-utility

It's advice was to:

1. Open BIOS
2. Go to Advanced -> Boot -> Secure\Boot -> Key Management
3. Delete the PK Management Key and only that key

It then showed Secure Boot State switching to "Disabled." Unfortunately, mine switches to "Setup." Perhaps these two are the same thing and I actually do have Secure Boot disabled, but an issue unrelated to this question and its answer persists (which is why I have doubts).

Is "setup" the same as "disabled"? And if not, how do I get to "disabled"?

Answer 1

It turns out that "setup" does in fact equate to "disabled".

The steps above are functional, and one can verify this with:

• In a unix system, either of
  • mokutil --sb-state
  • or dmesg | grep -E 'secure|nvidia'
• In windows:

Answer 2

No. Here is the correct answer: Change OS Type to Other OS

Note: Some newer Asus Bioses allow you to just toggle Secure Boot On and Off. Note: You can also try enabling CSM "Compatibility Support Module"
