Stop page template being used again?

I’m struggling to find an answer to this one.

When creating a new page in Kirby, I want them to be able to select the Template page only and not the home page, error page etc.

At the top of the Home Page yml file I have:

title: Home Page
options:
    duplicate: false
    delete: false

But this doesn’t seem to stop the home page being duplicated when creating a new page?

Has something maybe to go in the site.yml file instead?

Found it for reference for anyone looking in the future.

In the site.yml file where you create the new page under drafts, you can add the templates there.

drafts:
    type: pages
    label: Draft Pages
    status: draft
    templates:
      - template

This only allows them to create as template with the ‘Template’ page I have created.
