Is there a way to exclude a product from showing the tickets fields?

I have two product types in my shop: Tickets and donations. Now if someone makes a donation of say 15$ it's a bit strange to have to enter a name and mail address in the checkout process. Is there any way to exclude a single product and not tread it as a ticket? Screenshot for clarification: Thanks a lot for this plugin! I really appreciate your time and effort for this!
