You can load them as add-ins in exactly the same way. Put the templates in the Word Startup folder - If you have not changed the preferred startup folder it can be located (in English language versions of Windows) by typing
%appdata%\Microsoft\Word\Startup
in the Windows File Explorer Address bar and pressing Enter.
Then restart Word. The toolbars will appear on the add-ins tab of the ribbon.
Or you could recreate a new template with a custom ribbon tab -
