Set Chart Default to Hide Values

I have a few comparison reports where we would not want to include the values. I know they can be hidden after pulling but by then they've been seen which is causing both a distraction and unnecessary friction as they are touchstone data to help us make adjustments where needed within our systems and processes.

Is there a way to set a custom default, per report or chart, to automatically hide the values?

Or is this so simple I'll be smacking my head when someone answers?
