As above, rope or ratchet straps from a rafter work well, but I’ve seen people us a pair of step ladders across the front end of the bike with a rope from the top to take the weight.
Chocking the crank case seems to work, but makes me feel uncomfortable waiting for the sound of cracked alloy castings
