How to remove "message was pinned" message?

Hello fellows,

happens quite regularly here, I setup a new channel with some guides or whatever text and pin the most important messages afterwards. Now I’m getting these annoying “a message was pinned” messages which also quote the whole message. This makes the whole channel confusing, is there a proper way to get rid of these auto created messages?

Best regards
