Question on how to hide a form.

How do I hide a form x from the user? There is no option to set a form invisible when rearranging links. I only want this form x to hold data. Form x is not a data entry form. I have two other forms, y and z that I use to enter data into form x. Form y and z do not store their data in their respective forms. Form y and z simply create and update entries in form x.
