How to enter factory mode on Insyde bios (acer)

I was disassembling an Acer Helios 300 317-52 and noticed after it sat for a long time with the CMOS, battery, and a module labeled vendor being unplugged from the motherboard, it would only boot to a black screen, then shut off. I tried going into the UEFI firmware and there it was, a red UEFI firmware with Factory Setup displayed (or something like that), with a lot of options. Is there any way this can be reproduced, as I couldn't get it to work? Does this exist anywhere or is it documented, as it seems weird something like that exists? The UEFI firmware is original never changed/updated
