This can be achieved just setting the required to false - and this is excatly what you want to do.

The documentation wiki says

"When a field is not required, the validation rules do not fire"

Can we seperate the concepts of "required" and "validation"

so that if a vaue is entered in to a field it is ALWAYS validated

based on Edit Rules independent of whether the field is "required"

or not.
