Drilling holes will introduce swarf into the filter. There is a small chance this will get into your engine. Driving a screwdriver into the filter casing seems a whole lot cruder, but reduces (but does not eliminate) the chance of creating swarf or other particles.

Just my opinion. I've never changed a filter on a 201 2.6. The 201 2.0 I had was the easiest filter I have ever changed.
