I've looked everywhere and can't seem to find where to remove the feed filter "Text Posts" from the filter list in the publisher. I have a requirement to disable text posts. If this needs to be done by permission / profile thats fine as well. Chatter post is hiddin anyways so it does not need to be shown.

Figured this out after removing feed items from the page layout. It ended up being the Case Notes... not sure why its called text posts, it should be called Notes!
