ASUS ROG Zephyrus S GX531GX BIOS function unlock

[nanuq]

Hello guys,
Recently an issue wit ASUS ROG Zephyrus S GX531GX happened - a soldered ram (8Gb) gone bad (memtests were made, thousands of errors with it and permanent crashes with "memory managment" error) making PC crash and I need to disable this broken thing somehow.
I was trying to disable DIMM0 with AMIBCP but the saved file at the end is not supported by EZ Flash 3 or WinFlash (which says it is not UEFI BIOS, dunno why).
At this case I suppose its only a sigle option to disable (isolate) damaged soldered ram via BIOS and proceed with valid 32 stick. Thus, BIOS doesn't have Extreme mode to do this.
I'll be greatfull if someone could kindly help me:

1. To unlock the DIMM disabling feature in BIOS.
or
2. To save BIOS with appropriate extension with already disabled DIMM0 to use with EZF3.

Original BIOS (from the ASUS web) is herewith attached.

Thanks in advance!

I could try to let these options that you need appear in the bios.
First make a bios dump with this tool then attach the file. (Run dump.bat as administrator.)
