Using these two files

/etc/netplan/05-netplan-rj45.yaml
network:
 version: 2
 renderer: networkd
 ethernets:
  enp0s31f6:
    dhcp4: true
  enp3s0:
    addresses:
      - 192.168.0.210/24
    optional: true

/etc/netplan/08-netplan-wifi.yaml
network:
 version: 2
 # renderer: networkd
 ethernets:
   enp0s31f6:
     addresses: [ 192.168.2.2/24 ]
 wifis:

     dhcp4: yes
     access-points:
       "WaveLAN IAU":

Netplan merges the two configuration files, seems to work fine, except wifi.
