I did some more digging and I found someone that suggested passing through the entire USB controller, rather than mapping a device through Proxmox to the VM.
I removed the USB passthrough on the Ubuntu VM and instead passed through the PCI device: Cannon Lake PCH USB 3.1 xHCI Host Controller.

This has brought inference times down to <10ms AND CPU usage is averaging 12-15% usage for just the Detector CPU Usage.
Overall VM CPU usage has dropped from averaging 40-60% to 20-40%.

I believe that this issue can be closed since this was certainly a hardware issue and not a Frigate configuration issue.
