Unfortunately, it’s not possible to control filter pane interactions the way you can control slicer interactions. A filter that is set in the "on this page’ area - will impact all of the visuals on the page.
If you absolutely cannot put a slicer on the page, then you will have to modify your Text Measure to ignore that particular filter, with use of functions like ALL or ALLEXCEPT.
Alternatively, you could consider putting the slicer onto the page and editing the interactions as suggested above, and then add a bookmark that hides the slicer when the button is pressed. A second bookmark with a more discrete button could be added to return to the view with the slicer.
This would require training your users to create the PDF only after the hide slicer button was pressed.
