Custom Tour Right Sidebar

Good Morning

We would like to ask if it is possible to change this default sidebar that appears at every Tour Page.

Instead of this form, for some Tours we would like to add another form with custom fields.

For exemple instead of the booking form , we woul like a diferent costum form, depending on each tour. for exem,ple in on tuor we would need booking form, but in other tours we would need only a contact form

Tell how to make it

Thanks
