Yes both ZHA and Zigbee2MQTT support ser2net (serial to network proxy server) type remote Zigbee adapter via socat (socket cat) out-of-the-box by pointing the application (client) to the server.
If you have already a pre-made network-attached Zigbee Coordinator LAN adapter or setup your own serial proxy server the “server-side” with a Zigbee Coordinaor USB adapter athen you basically only need to replace the local serial port device path with the IP-address and TCP-port in the ZHA or Zigbee2MQTT application configuration on the “client-side”.
e.i. tcp://192.168.1.99:20108 for Z2M or socket://tcp://192.168.1.99:20108 for ZHA.

ZigStar LAN Gateway and Tube’s Zigbee Gateways come pre-configured but relatively not inexpensive.

DIY approaches include either making own Zigbee serial stream server with ser2net on a Raspberry Pi or hack a hackable Zigbee gateway, neither of which are as complicated as it sounds as there’s guides:
