The default behavior for VirtualBox, Parallel's Desktop, and I expect VMware is to automatically configure a default LAN adapter for the guest that automatically connects to the hosts Wi-Fi or Ethernet and Internet access.
You will have to verify with UTM documentation or the vendor about how they handle guest networking. If the Mac cannot recognize that AC600 adapter, then the UTM guest won't know about it either.
Third-party Wi-Fi adapters either are automatically detected by macOS, or they are not, and would require compatible vendor-specific drivers. I will not use one of these adapters if it requires vendor driver support, and have not needed any additional network adapter for Apple hardware in several years. When I did, the ongoing vendor support for driver updates was absent, and the next release of macOS rendered the adapter useless.
