Hello Carlos,

Yes, connect Pin 3 to the input of the GNSS module.

NO, do NOT connect any of the other pins to ground.  They should all be floating pads. You can place pads under pins 1,2,4,5,6 on the opposite side of the board and run a through hole via to them for better mechanical strength but there should be not ground underneath or around the antenna.

Best regards,
