The pressure plate spins with the crankshaft whether the clutch is engaged or released. It would be possible to simply unbolt it from the flywheel and run the engine with it hanging on the transmission input shaft without any further disassembly. That would also keep the clutch plate from turning. Just loosen up the clutch adjustment several turns or disconnect the linkage to give the throwout bearing plenty of room to move back. Starting the engine without a flywheel ring gear attached would be interesting to watch!
