[Request] ASUS Strix Scar 16 G634JY BIOS to Support 2x64GB RAM

Device: ASUS ROG Strix Scar 16 G634JY, i9-13980HX
Goal: Patch FSP-M MRC to support 2*64GB 2Rx8 DDR5 SODIMM (128GB total).
Current status: 48GB 1Rx4 sticks work out of box for 96GB, but 2Rx8 64GB sticks hang at memory training.

I wonder:
Has anyone attempted this mod on G634JY before?
Is the RSA signature on this laptop BIOS known to be bypassable?
If there is a chance, I will dump the BIOS with CH341A and share it.
Do I also need to patch DXE capacity check like the old Z170 6700KES mod?
