My I350-T4 network card has 4 network ports, but at present, 3 ports are directly connected, and the remaining one port is not displayed in the unraid network port. How can I cancel the pass-through network card?

If you want the last port connected to Unraid and the others connected to a VM then you are going to need to get them in their own IOMMU group.

 

You may be able to do with PCIe ACS override: in VM Settings, or if you card supports SR-IOV as per this guide.
