Not a ticket product
RSVP is for an event that is not selling tickets. Turn it on and ticket checkout is off. The two do not run on the same event.
RSVP
Switch the event to RSVP and the public page collects a guest list instead of taking payment. Ticket sales and RSVP do not run on the same event.
An add-on, not a ticket
RSVP is its own guest list. It is for nights when you are not selling tickets.
Your questions on the form
Collect a name, an email, and whatever else the night needs before they are on the list.
A QR at the door
Going guests get a pass the admin app can scan, separate from a ticket QR.

The form you write

A pass at the door
Going guests get a QR the admin app can scan. That pass is separate from an event ticket QR.
