What Jeff said. I can understand why a court might not like the idea of joint custody unless the parents agree to it, as it could well be asking for years of conflict. But sole custody does not mean that there isn't "visitation" or "parenting time" spelled out. Unless there is a very good reason no court is going to accept an agreement without it. And a parent who has sole custody and tries to eliminate time with the other parent could well end up losing custody, or even being held in contempt of court.
