I think it's easier to parse AIS stream on pi4 and just write custom (proprietary NMEA sentense for M5Stack) to display it via same
code on M5Stack display.
Using SignalK keys like "/vessels/<RegExp>/navigation/closestApproach" would work for that, but you'd have to have something doing the calculations for you. OpenPlotter in it's basic configuration won't do that, but I did notice a couple of AIS-related apps in the SignalK App Store that might help.
