No Display after switching to Ultimate with Armory Crate

Hi all, I was Switching SSD and I mistakenly switched to Ultimate in Armoury crate before nvidia drivers was fully installed, now laptop turns on window log in sound can be heard but I get no display, not even from the HDMI i guess it's stuck on display from Nvidia only but drivers are not present.

I have tried using narator to switch back but couldn't find the graphic settings anymore, tried booting from a fully functioning SSD of the same laptop with all the drivers present, still nothing.

I am thinking of removing the BIOS chip and resetting it with CH341a progrmmer. Do you guys think it will work or it's a waste of time?

NB. I've also tried to restore bios to default through f9 and f10 keys, nothing works. The screen wont display anything either from screen or HDMI

This sounds like the iGPU/dGPU mux got stuck in dGPU-only mode before drivers were installed, which can completely kill display output. Resetting BIOS with a programmer is usually unnecessary and risky. Before that, try pulling the CMOS battery, disconnect main battery, hold power 30 seconds, then reboot. Also try blind-booting into BIOS using F2/Del, or plugging in an external monitor after Windows loads. If none of that brings the iGPU back, a full EC/BIOS reset via service center is safer than flashing the chip yourself.
