You're not understanding it correctly.

There are FallbackDNS servers defined.  But, these are only used in the event that a user fails
to configure DNS servers or a broken DHCP server fails to supply DNS servers to the system.

FWIW, systemd-resolved.service is enabled by default starting in F33.  I believe an upgrade to F33
will also enable this.

However, you can always easily restore the previous behavior with Network Manager:
 
sudo rm -f /etc/resolv.conf
sudo ln -sf /run/NetworkManager/resolv.conf /etc/resolv.conf
sudo systemctl disable --now systemd-resolved.service
sudo systemctl mask systemd-resolved.service
sudo systemctl reboot

The key to getting good answers is to ask good questions.
