Yes, the USB LAN interface in EIZO monitors is usually suitable for use. For authentication during software deployment and system maintenance of client machines, we recommend using secure and unique GUID/UUID (Universally Unique Identifier) instead of MAC addresses.
Note: The use of MAC addresses can be incomplete because NICs such as USB LAN adapters, docks or monitors have their own MAC addresses and computers without a LAN port do not have a MAC address of the NIC. In addition, incompatibilities can - not infrequently - occur between hardware from different manufacturers. The use of GUID/UUID is manufacturer-independent.
GUID/UUID authentication for PXE-initiated deployments can be set quite easily in System Center Configuration Manager.
The following chat describes how it works: Reusing the same NIC for multiple PXE initiated deployments in System Center Configuration Manager OSD - Microsoft Community Hub
