Place a via where you want a hole, then mouseover it and hit Control-H to turn off the copper. Set your desired drill size with Alt-S and Shift-Alt-S.
Note that many fabs charge extra for unplated holes. It's easier, and often cheaper, to give it a plated hole. The annulus acts to keep copper traces away from the screw/nut/washer anyway.
I can seem to change the hole size
