2015. Can I just loop the high side and low side can bus wires? Does it need the injector data to run or will it just throw a code that can be turned off? I know it’s been done on the LMM, but wasn’t sure if the newer stuff is any different.

No glow plugs anymore, just cleaning up the engine bay. Minimizing components and wiring.

Yeah, going to have to turn off the codes and maybe zero out the glow plug/grid heater tables in the tune

I've done it on a lmm. Loop the canbus wires back together. It will still throw a soft code and the glow plug light will stay on
