GPU Passthrough to VM not working

I am trying to setup a Ubuntu VM on my Nas (TrueNas Scale 23.10)
I have 2 GPUs on the host, a GT210 and a Arc A750.

The VM is running Ubuntu 22.04.3 with the HWE kernel

If I try to do it the proper way (Isolate the A750 in the settings and select it for the display) it will fail with this error message: Method 'get_pci_ids_for_gpu_isolation' not found in 'device'

If I try to directly passthrough the PCI ID as a PCI device, the guest OS will see it but won’t load drivers and it shows up in lspci as VGA compatible controller: Intel Corporation Device 56a1 (rev 08)

How do I get the Arc GPU working in the VM
