I think there are more than one. One thing is to check what is enabled, then
disable or uninstall whatever owns the unit(s):
systemctl list-unit-files | egrep 'net|dhcp'
Do the same with whatever "manages" /etc/resolv.conf, and create a regular file of
your own design.
I don't use VMs, but I did several hours ago instruct several hours ago using
systemd-network to setup static IP service for a *buntu user who couldn't get
netplan sorted:

I've been using systemd-network static IPs on everything for several years,
including Bullseye.
