Not that I have seen. If a pax file exits in the folder, the tab will be shown, so it's an all or nothing deal, not user selectable.
For each application/tab, there are separate PAX files.
You have to edit the individual PAX file. I checked it for Modeling and Drawing tab, Just add "<! --" in PAX file (Comment out for XML) as shown in the image. Edit the respective PAX files, Save and restart NX, you will not see those tabs.
