There may be an easier way, less intrusive.

Edit /etc/netplan/01-network-manager-all.yaml and make it look
something like this:

network:
  version: 2
  renderer: NetworkManager
  ethernets:
     eth0:
        match:
           macaddress: 00:2b:67:2d:21:ee
        set-name: eth0

Add more stanzas for other interfaces you want to rename. And obviously
use the MAC addresses of your own interfaces!

Be aware that there are some (generally pretty obscure and unlikely)
situations where renamed interfaces can lead you up the garden path,
but for user-land operations and scripts, this works fine. I have not
had any issues.

It also won't help you if you are configuring your interfaces outside
netplan.

Full information about this is in "man netplan".

Regards, K.
