Mel commands to reload the Render Settings


Hello everyone, I’m trying to find a way in MEL to FORCEFULLY reload the RenderSetting json preset. Does anyone know a trick that would force maya to reload that? I need to do so because everytime i render something from command line i also change some settings in the render.json preset loaded into my scene but those changes get ignored because it probably doesn’t reload the settings everytime i render something.
Thanks for the help
