Have you ever had a working PC that wouldn't go into the BIOS mode?

Have you ever had a working PC that wouldn't go into the BIOS mode?

How did you resolve that issue?

1. The Windows machine boots to POST & then Windows 10 just fine.
2. Once booted to Windows, the USB keyboard & mouse work just fine.
3. But I can't get the PC to respect the BIOS F10 key press.

These are the key presses I know used to work:
o BIOS Menu === F10
o BOOT Menu === Escape
o DIAG Menu === F9

And yes, I'm pressing them (all the time) specifically at POST
o When it says to press "F10" to get into the BIOS.

It's like the keyboard isn't even there...
o The BIOS battery is only a few months old.

The reason I want to access the BIOS is I need to change the HyperVisor
settings for my AMD-based Foxconn motherboard for an Android emulator:
