No, I don't think so. But more importantly, see if you can find in the cleaner manual how one determines the cleaner's performance. Sometimes it's expressed as how fast its wheels are turning (revolutions or feet per minute sort of thing). Sometimes the cleaner comes with a little gauge to measure pressure or flow (my suction cleaner did, not sure about pressure cleaners). If the cleaner is performing correctly at the main pump speed you prefer to use, then you're good-to-go.
And
@guinness is correct, most pressure cleaners need both pumps to be running, the booster is correctly named, as it is boosting the pressure supplied by the main pump to what the cleaner needs. Which is why I got rid of both my booster and my pressure-side vac, had the cleaner line replumbed to suction-side and installed a suction vac. Works the same, but I don't have to empty the a bag, no tail spraying my windows, and no extra pump.
Others here use robots, which require no pumps to be running.
