Forcing an opponent to expand out of bounds

I’ve seen some teams online use curtains on their robot mainly to block opponents’ expansion. Is it legal to design some sort of curtain or obstacle that ricochet an opponent’s expansion out of bounds? I believed that it wouldn’t count as a forced disqualification since the opponent would be in control whether they decided to fire their expansion or not.

What does the game manual say? What are the rules regarding expanding out of the field, and forcing your opponent into a DQ, and how do they overlap?

Please come back with your findings so other people who have the same questions as you can see the correct answer.

That would be a correct assumption.
