If you need Page view (from SPPB) without typical template elements (header, footer). And you have template based on Helix Ultimate, all you have to do is...
- Go to Template Options
- Basic > Header > Predefined Header : OFF (and whole header will disapear)
- Layouts > and delete the footer section (with footer1 and footer2).
- You don't have to delete/change grid on middle section, becuase if no left/right modules will be used, component will use whole area. Alternatively you can enable the Fluid width (On) in Row Options.

Note! Remember to keep section with the component position (!) without that nothing will work.
If you have different developer template, it should be also possible, but beyond our support.
