Append Only HIdden Field Form Data

I’m trying to pass through my url parameters through my page using the hidden fields on the form with a single email collection but the form also appends the user’s email to the URL. Is there a way I can do this without appending the URL and only passing through the URL parameters?

One of the ways would be to create another page - call it interstitial page. Use this page in form actions. Let all fields pass to this interstitial page. Fetch the field names and values in this page with a JS and redirect to your desired page with your desired fields appended.
