Form logic can only be applied based on radio buttons, dropdown, or check boxes. Because of this, you can't use the logic on calculated fields.
The only thing I can really think is that you could use Fusion to achieve something. Off the top of my head - You could create an automation that would validate the calculated field and then update a radio button to allow the rest of the form to populate. But that could only really happen after the form is saved. The user would have to be able to save the form and then also have to access it twice.
