Wanted to ask if there's any command that Creeper does not explode / destroy blocks. Have a world wants to do something with Creeper but they should not destroy everything.

Creepers are still exploding, but it does not do any harm.

Thank you for the helpful answer
Also important: Enderman can't record blocks anymore and villagers do not grow any resources (wheat, carrots, etc) anymore!
