I've never any sort of pre-print processing/calibration on my Prusa MK4(S), other than cleaning the build plate. This sort of hand-holding really isn't required anymore on the modern printers. Slicers also come with presets for different filaments these days, which generally do a reasonable job and knowing about temps & co is largely optional to getting going.
