Space settings for External Share can be accessed through the "Space Settings" menu on a Confluence page, and are found under the "Add-ons" tab
The "View Links" page shows all links created in the current space
The "Enable External Share" setting can be used to disable all links in a particular Space
This can be very useful if you have a private Space (e.g. a HR team) that you want to make sure never generates any External Share links
If you have existing links in a Space, when you disabled External Share, those links won't be deleted, but will be disabled:
If anyone tries to access an existing link they will see the following message:

Users that can create, edit and delete External Share links are defined in Global Settings
By default, any logged-in user is able to create, edit and delete External Share links in any Space they have permission to access:
