We have added this recently in #3887 (v4.8.0 should have it).

Please test it out and let me know if it works out for you.

Note that EOS does not show the address familiy configs under the VRFs for peer-groups. The config will show up in the global context, but if a VRF neighbor is associated with the peer-group, the peer-group activation will be applied in the VRF AF as well.
