No, a wife can not deny her husband from marrying more than one woman.
The base law about multiple marriages is that it is permitted:
فانكحوا ما طاب لكم من النساء مثنى وثلاث ورباع فإن خفتم ألا تعدلوا فواحدة
Then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one.
— Quran 4:3
