You would need a second view which is read-only or what ever you wanted.
Then you need a field in your form to track the state of the form, submitted or not. There may also be a field which would be blank on a new form and has a value after submit, this would work for detecting whether the form was new or submitted. Once you have your conditional, put a rule in the open rules, found in form options, which has the condition and if true switch views.
This will give you what you are looking for.
