Does Anyone Know A Reliable Backdoor Way To Access BIOS? (Edit: I Worked Around It)

My function keys are disabled, and apparently this can only be fixed in BIOS.

Without the function keys, BIOS can't be accessed by the normal methods.

There is supposed to be a way to do it from Windows 10, but all the instructions I've found do not describe the operating system I have. I'm supposed to go into settings and select "Security and Updates," but that setting doesn't exist. Searching for it in Windows Settings produces no results.

Trying the "Shift Restart" method also doesn't work (I assume because the function keys are disabled, but I don't know why.)

After several hours, I've accepted that I'm not going to find any instructions that work. I'm guessing there's an emergency backdoor for situations like mine, and I'm wondering if any tech people know a way to force boot the BIOS startup menu that work when everything else is disabled.

EDIT: One method did end up working - Holding down "Shift" while clicking "Restart" but with the additional info "Keep holding down Shift until Advanced Boot Menu Option appears."
