Hide wpmudev plugins custom fields

Somehow the long list of custom fields created by plugins, that are not being used when writing a post, are distracting and even hide the custom fields that are created to be used when writing a post.

Is there a solution to hide these and only show the ones that have been created to be filled in by the author?

(I think these custom fields are from Hummingbird, Defender, and Smush Pro)
