This is not possible by setting an option, but you could write a custom function or a plugin to validate status changes.
Of course, you still might get notes containing nothing more than a blank, a single character or some stupid words.
Keep also in mind that sometimes it does not make that much sense to write notes, e.g. setting status to closed and write a note "set status to closed" is no additional value.

Closing as duplicate as the request is covered by the requests in 0008941.

Yes, the reference to nonsensical values ​​is of course correct. I know that I can not prevent that. But I can encourage colleagues to think.
I will try a custom function. Thank you for the information.
