Prevent NVDA to reading certain text contents

[werls]

I'm working on a project for an accessible PDF and all tests are being performed by a consultant using NVDA (which is the most commonly used screen reader here in Brazil).

Some text elements in the PDF are being designed exclusively for traditional reading (such as a folio that contains information such as company and departments names and the page number). Therefore, ideally, this information should not be read by NVDA, as it seems counterproductive for the same information to be read on each page (the primary function of the folio is to guarantee the identification of the document page when printed and separated from the rest).

I'm using Adobe Indesign to create the PDF and there is an option to define a specific tag for the contents that should not be read by screen readers (the Artifact tag). It's a feature that works perfectly well for Read Out Loud, Adobe's native reader. However, in the case of NVDA, apparently all content identified as text is read, regardless of the use of the tag.

An objective way to avoid reading the text must be to convert it to outline or rasterize as a bitmap image. But this is a very time consuming job when considering a large volume of documents.

Is there any more practical way to prevent NVDA from reading certain text contents?
