Does anyone know how to disable the Print to File option in Calc? Basically I am trying to hide/prevent all access to viewing anything about file paths. This seems to be the only thing left that exposes this information.
I think you might be approaching this problem in a very awkward way.
If there’s a user on a system who is not allowed to see the content of certain files and folders, then that is something you need to deal with using the file system permission control in your operating system, and definitely not by trying to disable menus within LibreOffice that allow you to browse the file system (of which Print to File is not anywhere near the only one).
For example, if you don’t want other users to be able to see the content of your home folder, you need to make sure that they don’t have a read permission to that folder. How this is done depends entirely on your operating system.
Here’s an article on file system permissions on Debian. What operating system are you using?
