Remove “Delete cached content for this part”

Hello,
How can I remove the “Delete cached content for this part” block please? I’ve already used it and don’t need it no more. And it’s in the middle of the way and obstructing my styling process. I think there should either be a class to the div in question, so the user can remove it via css, or have an option in the plugin settings where the user can disable it if it’s not needed…
Thanks!
