Yes, but it's pinned to a driver version that I unfortunately can not use. That's precisely why I love your solution, it is the best way to do this.
I'm running 8 GPUs attached to a single CPU and that driver is a pretty essential part of getting this to work with P2P between as many cards as possible. The modded 4090 is a problem because the BAR1 it advertises (32G) is smaller than the VRAM so not all software is able to use it (you need two memory segments rather than a single 48G one to make this work). That driver is part of the solution for this problem.
