I experiencing the same problem. My two Ethernet interfaces does not get renamed. I want to accomplish the following.
eth0 => eth1 eth1 => eth0 Basically switching names between the Ethernet interfaces. I had the same exact setup on 18.04 which worked. You can find some information about my system below. Please let me know if I should provide more information. == networkctl(1) == # networkctl status eth0 WARNING: systemd-networkd is not running, output will be incomplete.

And it should work based on the systemd documentation. I googled the issue but I didn't find anything interesting instead that I should run "update-initramfs -u" but that didn't help. I tested that this doesn't work both on Ubuntu Desktop 20.04 and Ubuntu Server 20.04.
