[NumNum]

If it isn't configurable in admincp, is it possible to tweak the below discussion using css?

That's a user level configuration you can't fully control. You can change it in the database of course but ultimately users have the option to change it as they wish.

And it's not possible to change it in CSS either. But even if it could, it would only for display. CSS obviously can't change anything in the database.
