So I tried a BIOS VM, freshly created from scratch. Reinstalled Windows 10 and was able to get the NIC and USB passthrough working fine. When I removed the VNC Graphic device and Video Display, then add the NVIDIA card (graphics and audio) the machine doesn't boot and needs to be forced off. Even re-adding the VNC Graphic device and Video Display (so I can see what is going on) fixes it allowing it to boot (even though the GPU devices are still present). I can confirm when it boots normally that my TightVNC connection works. But I'm blind when just the NVIDIA devices are present so no clue WHY it's not booting.
