There is an article on this problem (Remove Knowledge Feedback section ) but it dates from more than 5 years ago. I tried to add the property as suggested in one of the replies but it doesn't change anything. Possibly things have changed since V3. Anyway, I think that being able to remove this feedback section is valid because our articles are just informative, no feedback is required and we don't follow up on feedback, so removing the section seems to be the thing to do.
