Sharepoint 2013 - Script to Allow Sharing Site or library only to administrators

Question

I'd like to disable sharing to all members except administators on ALL Site Collections. Is there a Powershell command that match my request ?

Or maybe only admistrators will approve sharing request.

Thank you for your help

Regards,

I don't think it's possible to disable sharing for non-owners by using PowerShell in the SharePoint server.
