Yes, that is illegal, and a huge safety concern. What happens if your drill goes a little too far when making that hole? You drive right into the battery, causing damage and a potentially dangerous situation (battery could internally short and catch on fire/explode, it could leak/spray battery acid, etc) For the sake of everyone's safety, there is a blanket safety rule against any modification of the battery beyond attaching the leads with appropriate fasteners.
