(SP 2013) Can sharing permissions be changed to suit a specific document library?

I’m a bit newer to SharePoint and couldn’t find much on this area anywhere else. We have a sub-site that holds a document library we’d like to manage sharing permissions on.

Essentially, we want to restrict regular user’s ability to share documents within this library and have a manager user share from there when needed.

I’ve heard that with SP Online you can manage permissions from Site to site, not in the fashion we need but it still exists.

So I was wondering if this even possible and if so could it be done without affecting the rest of the site?

Thanks in advance.
