Gigabyte MZ31-AR0 rev.1.x bios chip upgrade

Does anybody have some experience wit this motherboard?

I could get this motherboard for a very good deal (with an AMD EPYC 7551p and 128GB Kingston DDR4 2666Mhz RAM), but I would like to update to EPYC Rome (7002 Series) in the future.
I know, that this motherboard officially does not support Rome, but as I can tell so far, the main (or maybe only) difference between the rev.1.x and rev.2.x boards is the bios chip.
However, there is a possibility to physically replace the bios chip (warranty loss!). The only reference about this topic, what I've found is:

Has anyone done something similar to this?
What do you think, is it possible to make the rev.1.x board compatible with Rome?

(I want to use the system only for CFD with OpenFOAM and with big meshes above 10M cells and more)

Physically replacing the bios chip might be possible. But I have never seen it done. Let me know if your have success with that

Here is a less invasive method to get Epyc Rome CPUs working on rev. 1.x motherboards: https://forums.servethehome.com/inde...rome-es.28111/
Although that might only work for the cheaper engineering sample CPUs. Not quite sure about that yet.
Edit: allegedly, the method also works for retail CPUs, even with newer bios versions.
