Disable scrolling/fullpage while filling out a form

### Description
I've got a form inside a fullpage-section and it works fine on desktop … but I haven't considered, that the virtual keyboard will use half of the viewport :-)
So when a user clicks a field the last 3 fields are hidden by the virtual keyboard.

Is there a way to disable fullpage when the user edits a form or is on a particular section with my form?

Perhaps, other solution would be make the form outside (new window, modal), have a step-by-step-wizard to show each field on its own, or maybe double the size of the section to allow for scrolling.
