Finding Unmanaged Clients Without Configuring Unmanaged Detectors?

Is there a way in the SEPM console to view clients that are unmanaged without having to configure unmanaged detectors?  In my search I found this: 

"...Symantec Endpoint Protection Manager uses several methods to locate unmanaged clients. It can still locate unmanaged clients if no Unmanaged Detectors are defined, but the results are more accurate if there is an Unmanaged Detector on each local network segment...."

But it doesn't go on to say how to do that. It only talks about configuring unmanaged detectors.
