Seems to be similar to setting the password for the console. This is
(as long as I know)
also not possible to configure via start command.

Instead of virsh I use my own startskript, where I read referencing
options from the vm
config file. Then depending on their value the skript sends various
monitor commands
(like console password).

What you could do is simply append a

 '&& echo "set_link virtio-net-pci.0 off" | socat - UNIX-CONNECT:<path
to your monitor socket>'

to your start command for the vm.

Steffen
