Wife moved out, can she legally come back in the house if I don't want her to?

My wife and I have recently separated and are in the middle of divorce. She still has a key to the house, and I’m going to change the locks. However is she legally allowed to come back to the house even without my permission?

She moved out about 2 months ago and has been living with a friend. I own the home, and her name is not on the loan/title. This is also in Las Vegas, NV.

I simply do not want her showing up randomly, or when I’m not there. It’s probably better that way for the both of us.
