Hi,Use metadata schema instead of metadata profile and give use servlet registered resourcetype in json path.AEM Content Fragments: Dropdown Limits in Metadata Schemas?

It does not work with registered servlet, You need to use json.

You can generate json using scheduler or event handler or run time whichever suits you case

or use javascript to call servlet and generate options when metadata schema is loading.
