Help Reset UEFI BIOS with USB2 disabled

[dyang94]

I disabled all USB2 ports by mistake. Was around 1 AM and I wasn't thinking straight.
The boot option is set to UEFI only.
Clear CMOS button doesn't seem to be on this MB.
Taking out the battery and cutting power overnight hasn't reset the BIOS.

I heard you can automatically launch programs with autoexec.bat in DOS. Is there a similar thing in UEFI WINPE?

There is winpeshl and with correct parameters I could flash the BIOS. Did not reset the BIOS though.

Added /N to clear NVRAM and it did reset the BIOS.
