To be on the safe, safe side, you could just remove the valve so that the pump is constantly on full bypass.
Actually, once you get above around 5-6k the pump pours out of the pulley shaft if the Hicas is plugged. You need to "castrate" the pump by pulling out the fins like FF said) if you plug off the back of the pump.
You would also be leaving dead weight on the motor for no reason if it was left in there.
