What you are describing seems to be the "Simple Command Card". If you want to change it only on your own Account, go to Options->Gameplay->Enable Simple Command Card and untick the box next to it.
If you want to do it for everyone playing a map, you should use the action "Override Player Option" and set up the Values like this: Override [Enable Simple Command Card] option for [(your desired player)] to [Disabled]
How do you remove the '(A) the [mouse click] to Attack' message on the command card on units/buildings that can attack?

Just what I needed, thanks!
