Can a lady stipulate in the nikah contract that her husband may not enter into polygamy?

From what I understand, in Islam marriage is a contract. And conditions can be set in it breaking of which can be grounds for divorce. Thus is it acceptable or considered makruh for a female to stipulate that her husband not marry another woman while married to her i.e **deny him to be polygamous** Or would this make her a sinner as she is making something that is Halal for him to be impermissible?
