This what I use, when NIC MAC is changed by a new install.

#!/bin/sh
UUID=$(nmcli -t  con show | grep Wired | cut -d: -f2)
nmcli connection down $UUID
nmcli connection modify $UUID ethernet.cloned-mac-address
"xx:xx:xx:xx:xx:xx" #put here your preferred MAC address
nmcli connection modify $UUID -ethernet.mac-address ""
nmcli connection up $UUID
