Aura Pro PDF Zooming

So a question for all of you who know how to better read PDFs on a Kobo device (Aura HD specifically)

When I open a book/document, the reader shows the page number on the bottom of the page - using up about 8-10% of the available reader space.

I welcome then knowledge of the page I'm on, but this removes real estate space from actually viewing the content I want to read.

Is there a way to disable the display of page numbers on the bottom of a PDF? - without manually zooming in?

Thanks for any help!
