Hi Eduardo,

Yes, you can connect the PAD to GND.
I think you can connect NC pins to GND as well since the data sheet states "No internal connection". However I will verify this and let you know the result soon.

Eduardo,

It is safe to connect NC pins to GND. There is no internal connection to these pins.
