What you can do is disable the Public Form option so your form won’t be public anymore.
1. Go to your Pipe’s Settings and select the ‘Start Form’-tab.
2. On your Start Form Settings, scroll down until you find the Advanced Options. There you’ll find the ‘Share this form’-box, go ahead and uncheck it. After unchecking the Share this form box, your Start Form is no longer public.

Pipefy Tip: Disable your form even more easily via a shortcut! Click 'Create new card' and look for the Share button on the top right corner of your screen

Uncheck the box and your form is no longer public.
