The NMEA driver has at least some PPS logic built-in, initially to
overcome the default limit on allowable offset between the serial time
stream and the PPS signal.
Anyway, afair my 18LVC does not use the ATOM driver...
No, I have only configured NMEA plus a single network peer, and it is
currently rolling along with 1-2 us offset and jitter.
