Hide track graphs when chains is applying

Is there a way to stop track redrawing or to hide track graphs at all when chains is applying to multiple files? Those redrawings often take major amount of time in case of big files and long chains.

Not in Audacity. What you are requesting amounts to running Audacity as a command-line application in silent mode and it can’t do that. What effects are you applying? You might be able to use SoX.
