Is it possible to have 10Gigabit network support on a macOS VM?
I would start with a trial license (free) of VMWare ESXi to enable hardware support for USB-C and Thunderbolt adapters.

There are many home labs where thunderbolt to 10G Ethernet and 8G Fiber work even when those adapters are not on the official hardware compatibility and support matrix. Newer Mac mini have 10 GB Ethernet built in as well. I’ve never seen a 10 gig link saturate, so we just put several VM on the same hardware in practice.

Until we’ve got fast enough NVMe storage, I can’t imagine needing more than one ten gig ethernet adapter unless I was doing rack mounted workstations and enterprise class servers.
