network-interface ifconfig mac-address spoofing

                          In Red Hat Enterprise Linux (RHEL) 8, if someone does ifconfig eth0 hw ether abcd12341234,

*all I know is ifconfig and ip -a*,

so then is there a way to reliably get the real MAC address of that eth0 interface and if so how?   ... other than for example rebooting to a Linux live CD coming from a reliable source to be sure the MAC address of the interface hasn't been changed.
