I don't seem to be able to delete policies for templates in Adobe Experience Manager 6.5. I can keep adding copies of a policy, but I don't see any way to remove them. Does anyone know if this is possible either through the browser editor or CRXDE?
you can read this article I found on the web https://myaemlearnings.blogspot.com/2018/03/policies-in-editable-templates.html
For example, if you want to delete the policies assigned to a container, the path would be:
/conf/{name}/settings/wcm/policies/{name}/components/container
