This doc will show you how to hide an entire Documentation from the index page. This requires admin privileges.

1. In your admin panel go to Tools > Export.
2. Select Docs and click Download Export File
3. Open downloaded .xml file in a text editor.
4. Find your Documentation within <title></title> tags.
5. Underneath you’ll see the ID within <wp:post_id></wp:post_id> tags.
6. Copy the number inside the <wp:post_id></wp:post_id> tags.
7. Enter the edit mode for the index page.
8. At the bottom of the page, there is this piece of weDocs “shortcode”: [wedocs] or [wedocs exclude="..."]
9. Add the post ID from step 6 into the exclude property, separating each ID with a comma.
10. Update the page and you’re done.

This is currently how the Notes documentation is being hidden 😀
