ATC operating without radar would also have a good idea of the area you are operating in using VDF, assuming you are talking to them.
This guy is non radio (either not equipped with one or doesn’t want to switch it on) so VDF is a non starter.
Granted, he may have a transponder and even if he does switch it on there may well be non-commercial aircraft without TCAS doing the procedure.
Even if there is radar, depending on the aircraft type and position it might not paint on radar (assuming no transponder).
