Asus Vivotab Note 8 - Reset Bios

Through a series of downwardly cascading events I managed to make some Bios changes that yielded the unit booting to a black screen...no backlight. The unit has a Windows 10 installation. I can tell the unit is booting as I get the Windows startup sound. The various push button combinations are seemingly useless in absense of a display.

I have no problem opening the case. My question: Is there a way to reset the Bios equivalent to reset jumpers or removing the coin cell and momentarilly jumpering across that connection as can be done on desktops?

I'll appreciate any insight.
