With the DSG it depends on how hard you push the brake pedal once the car has stopped, if you press it just enough to hold the car it doesn't cut out but if you press a little firmer it will.
Unless it can be disabled with VCDS then no it can't, but as Dubber says if it only cuts out when in neutral and the clutch lifted then it's no big deal really? By the time you've put it back into gear your up and running.
