First of all, systemd-resolved is not used and enabled by default.
If you actually do use systemd-resolved, disabling the
fallback DNS server(s) is trivial.

Either edit /etc/systemd/resolved.conf and set 
FallbackDNS=

or create a drop-in snippet like this:
mkdir /etc/systemd/resolved.conf.d/
echo -e "[Resolve]\nFallbackDNS=" > /etc/systemd/resolved.conf.d/no-fallback.conf

Then run systemctl restart systemd-resolved.service.
