If you don't want the pay-in-full price to show on the Enroll Form, you can unpublish it on the Program(s).
Publish/Unpublish Pay-in-Full
Follow these steps to publish or unpublish Pay-in-Full pricing.
Step 1 - Open the editor of a Program by clicking the pencil icon.
Step 2 - Select "Pricing" in the left menu to go to the Pricing section. Click the eye icon to publish or unpublish the Pay-in-Full.
