Prevent sharing links by library?

Is it possible to prevent sharing links on a per-library basis? Is that a Pro-only option?

No, this is not possible.

In Seafile PE, you can strip a user of the permission to generate sharing links by changing the user’s role. But this is a global setting applying to all libraries.

Thanks suspected as much. In the pro edition, what is the level of granularity of preventing sharing? Per library or more granular?
