Injecting NMEA Data Direct... possible?

Hi there,
I’ve been digging through the various flags in pixhawk and more, in an attempt to inject NMEA strings into pixhawk, in the hope that something will convert those to RTCM and provide them to my here3 module. I think I just figured out that the u-blox modules cannot accept NMEA direct and must have it wrapped in RTCM… but please correct me.

Any chance this NMEA->RTCM internal to pixhawk exists? I’m trying to remove having a MAVLINK computer in the middle and go direct from a Sparkfun Facet into my rover.
