Basicstation clock drift, where to find station.config

I am having the same issue as this thread, " [BasicStation: “Repeated excessive clock drifts” and disconnect/restart after ~3 minutes]" (BasicStation: "Repeated excessive clock drifts" and disconnect/restart after ~3 minutes)

That thread is closed as the user found the solution. I am looking for where the station.config file is located in order to change “pps.” to true. does anyone know how to go about locating this file. I am very new to gateways and LoRa in general. Any help would be appreciated. Thank you in advance!
