You don't. Or, at least, you don't *effectively*... they don't understand. It's like yelling at a dog two days after they do something wrong: it doesn't make sense and it doesn't change their behaviour.
Autistic (and lots of other handicapped) people need their environment arranged so that they can succeed --things they aren't allowed to do are not available to them. At all. Things they can't handle are done for them. Et cetera. Like keeping small toys out of reach of small children so they can't inhale them or choke on them....
Discipline is 'teaching' that requires 'learning' to be happening. Without being able to engage autistic kids, it's very hard to stuff things into their heads. Harder even than convincing adults (with as much research as would fill an average house to prove it) that punishment does not teach what it's supposed to teach --quite the opposite.
