Those receivers typically only require a UARFT connection with GND, Vcc and RX.

Just search for NMEA in the forum. One example for simple ones: https://forum.micropython.org/viewtopic.php?f=18&t=7766&hilit=NMEA

Besides that you may as well use the pytrack board as expansion board, if you have that already, and connect the DHT sensor to that board. The pytrack board has a 10 Pin connector which exposes Vcc, GND and six GPIO pins, of which for instance P10 and P11 may be used for the DHT.

Since at the moment, I am using FiPY to send CoAP msg using NB-IOT which If mounted on the Pytrack will not leave any open pins for the DHT sensor. Does the fipy need to be mounted or it can be connected with wires.

Ans you know, the DHT just needs GND, Vcc and one data pin. And that is available on this IO header. See: https://docs.pycom.io/datasheets/expansionboards/pytrack/
