Getting RTK solutions over LTE w/o pc or bluetooth

I have a SparkFun GPS-RTK Board - NEO-M8P-2 (Qwiic) connected to my Redboard Turbo, with the SparkFun LTE CAT M1/NB-IoT Shield - SARA-R4. I can make it work by getting correction data through the computer and sending it to the GPS I want to use the LTE Shield to get the correction data from UNAVCO. Is this possible and has anyone coded it yet with Arduino? I need a self-dependent corrected GPS without connection to a computer or local base station. It must come from LTE and I don’t want to add another component to the unit.
