How to remove slug field from "Duplicate" dialog (works in "Create" dialog)

I’ve applied a small hack to hide the slug field in the Create Page dialog, which works as expected:

create:
  slug: void

However, when I duplicate a page, the slug field still appears in the duplicate dialog — which I’d like to omit as well.

Is there a way to remove the slug field from the Duplicate Page dialog the same way as in the Create dialog?

There is no blueprint option to configure the duplicate dialog. But it should be possible to overwrite the page.duplicate dialog in the site area: Panel areas | Kirby CMS
