Configure a page with both type = page and features of breadcrumb, sidebar, toc, etc.

[realfish]

For _meta.json configurations, is it possible to enable breadcrumb, sidebar, toc, etc. for a page of "type": "page"?

For example, is it possible to make docs.mdx (which is supposed to serve as the entry/index of docs/ dir) an item on navbar while retaining features of sidebar, toc, breadcrumb, etc.
