OK, thanks.
On another 20.04 fresh install (Desktop) I just see in /etc/netplan
the file 01-network-manager-all.yaml containing

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

So if I wanted to manage the network manually I could replace that
file with others to set it up as I wanted.
That's useful to know. Thanks.
