no MAC delivery to DHCP server in Rhel 8 dhcp client

I have a RHEL 8 virtual machine in vWare, which from the eth0 interface requests ip to the DCHP server which is a Windows operating system, when the RHEL 8 machine requests to reserve the ip, the dhcp server is not saving the MAC of the eth0 card in El which is in the "unique ID" field you are saving is a different combination than MAC, but this does not happen in rhel 7 versions, any suggestions?
