[REQUEST] Acer TravelMate P215-52G VGA OPROM / CSM Support

[ages2001]

Hi! I posted this topic before but nobody helped near ~7 days. Did I opened this request at wrong topic?
Anyways, I have a 2020 Acer laptop. Intel removed CSM / Legacy boot support, so I cannot change this setting in InsydeH2O BIOS. It is grayed out. But in past, someone in here modded my BIOS (.bin) and disabled RSA signature to flash modded BIOS. After this, I could change UEFI to Legacy boot. But this time when I change to Legacy Boot, my laptop bricks. After saving changes, laptop screen is blank and I cannot enter the BIOS. Even RTC/CMOS battery solution did not work. ONLY SOLUTION is flashing original BIOS file(.fd) from USB (FAT32 formatted) via Fn + Esc.
Maybe there is a problem in modded BIOS file or Intel integrated CPU or nVidia GeForce MX230 video card does not have a VGA OPROM. Is there a way to add VGA OPROM support (or disable GOP driver) to BIOS file?
