lenovo thinkbook 15 g2 itl disable onboad ram bios

[deejay_xb]

I have a lenovo thinkbook 15 g2 itl (working!) and in the .bin bios file i found the lines with 6.5.6.5...6, but i don't know what to replace with 00 to disable the onboard ram/memory, if someone can help.

i've attached the extracted .exe file, this contains the bios dump when opened with 7zip (the file is DOSFLV34_QS.bin)

also how to flash the modified bios? can it be repacked and flashed?
