When enabled, overrides whatever keyboard layout and always makes the
keys in the physical location of F2, F10 and F12 send the keycodes for
F2/F10/F12.
BIOS is supposed to enable this right after USB enumeration, so that the
BIOS hot keys always work, even if FN-lock is enabled or the user has
remapped their keyboard.
BIOS mode is exited either by the keyboard resetting or by sending the
disable message.
How to send:
1. Find USB devices with Framework VID 0x32AC
2. Filter by interface number == 0x01 and usage page == 0xFF60
3. Set HID report with the following body:
Enable: 0x00 0x0B 0x05 0x01 0xFE 0xFE ... pad the 32 byte buffer with 0xFE
Disable: 0x00 0x0B 0x05 0x00 0xFE 0xFE ... pad the 32 byte buffer with 0xFE
Where the first byte is the report ID 0x00
