Set custom DNS servers using Netplan and networkd

Please note, you’ll lose the Network Manager GUI using this method! I recommend my other methods below, but there may be a reason you need to use networkd.

CODE:
network:
version: 2
renderer: networkd
ethernets:
[DEVICE_NAME]:
dhcp4: true
nameservers:
addresses: [NAMESERVER_1, NAMESERVER_2]
