Here's a few options...

1- less aggressive disc
2- smaller diameter disc or reduce the effective diameter of the disc you have
3- reduce clamp pressure by either swapping to a weaker PP/spring or shimming your existing PP away from the flywheel
4- temporarily hold back some clamp pressure with your foot, basically ride the clutch out for 5-10 feet. Adding an adjustable spring loaded pedal stop can make it easier to consistently find the sweet spot in the pedal travel
5- temporarily hold back some clamp pressure with a timed mechanical device
