GPU Passthrough With GB 3070 Gaming OC

[RJ83 0]

I've worked through spaceinvaderone's videos on TS and still can't get past the black screen.  I've downloaded the appropriate rom, edited the nvidia header out, confirmed both the audio and video are on the same virtual slot and still no joy.  Has anyone been able to successfully get the card working on a W10 VM?  Full XML attached and I've tried loading the rom as both a .dump and .rom file.

 

edited for clarification: I should also note I was able to get the VM running prior to passing through the GPU and installed splashtop.  I have a monitor plugged into the card via hdmi (and a loopback dongle when it's not plugged in) and still cannot get this thing working.  Please help!
