Help with Kali VM hangs when attempting passthrough of second (identical) GPU

I am setting up a homelab and I'm running into an issue passing a second GPU to Kali. Both are GTX 1080

The first GPU is passed through without issue, and the nvidia drivers are installed and operational. When attempting to add the additional hardware to pass the second GPU (identical to the first aside from address) the VM appears to be running but nothing is shown on the console, not even a boot screen (also nothing appears to be output over via the gpu).

I can remove one card and add the second and it will boot to console without complaint, so i know both cards are working, just not together. I'm hoping someone can point me towards a solution or what logs I should investigate to find the conflict. My vimd.conf is below. It boots to console without complaint and the VM has direct access to the nvidia GPU.

Adding the second GPU by either hostpci1: 17:00,pcie=1 or hostpci1: 17:00,pcie=1,x-vga=1 leads to no boot screen on console (or through gpu).

I'm running 6.2-12 with community updates current as of today. Also, for what it's worth, I was able to configure and boot simultaneously 2 windows 10 VM's each with dedicated gpu and usb.

any ideas?
