Tweaking graphics to go even lower

Hi, I'm looking forward to play snowrunner but I don't have a great laptop but still, I can get 20~30 fps when unplugged and almost 30 fps when plugged in.

Is there any way to make the graphics of the game even lower using some config file? Like in ets2, there's a config.cfg file in the Documents folder, is there something similar in Snowrunner too? My own findings say no.
