I seem to remember that one was reporting if it was using the external vs. internal antenna and that would probably have been a $PMTK sentence. I was using an external antenna. When I use it with gpsd, is gpsd “aware” of that chipset and turning some sentences off ($PMTK)?

only RMC, GGA, GSV, GSV, GRS, GST, ZDA. So yes, it's one of the
$PMTK sentences pushing you over.
