It's not only NWFilter that will inject firewall rules. Depending on 
configuration it might also be the default network.

Unless you have a domain <interface/> defined so that it uses a nwfilter 
then no firwall rules are added by nwfilter code.

If you still want to remove nwfilter module then just uninstall it, e.g. 

dnf remove libvirt-daemon-driver-nwfilter libvirt-daemon-config-nwfilter
