Templates help remove a lot of friction from the creation process. However, customers can become confused when they see a template for irrelevant modules. So, what can you do to prevent it?
Hiding the template library is the perfect solution; this feature offers you full control over the template scope your customers see.
How To Hide The Template Library?
In the agency view, navigate to the Template Library section and access the settings tab (indicated by the gear icon).

Click the Customize for Sub-Accounts option.

Locate the sub-account you want to hide the template from and click the toggle icon.
Set your visibility preferences. Here you have two options:
Hide
To completely hide the template library from this sub-account.

Hide for specific products
This option allows you to select products you don't want the subaccount to access.

When using this option, select the products to remove from the drop-down menu.

Once the visibility scope is selected, click Save to apply your changes.

This will immediately remove the templates from the sub-account, preventing users from using or modifying them. This feature doesn't remove access to the templates for you or any other agency admin.
