Hi, gwrxy

Secure Boot on Nitro V15-51 (BIOS 1.31)

With BIOS 1.31 and Windows 11 24H2, Secure Boot is likely enabled by default and locked. Acer seems to have removed the option to disable it in BIOS, aligning with Microsoft’s push for stricter firmware security.

🔒 Why You Can’t Disable It

BIOS 1.31 doesn’t show the Secure Boot toggle anymore.
Windows 11 24H2 enforces Secure Boot for system integrity.
BIOS rollback isn’t allowed—Windows blocks downgrades for security.

I can't change any switches at all, that is, I press to change, for example, the time, but it doesn't turn on for me and thus I can't change the BIOS language.
I can't figure out if this is a laptop problem or if the BIOS is completely locked???
