You can turn off comments on individual articles as necessary. When you do so, the article indicates that it is closed for comments at the bottom of the article.

If you need to turn off comments for multiple articles at once, see Updating knowledge base articles in bulk or use the Help center API (Update Article). There is not a global setting to turn off comments for all articles at once.
Tip: If you want to hide existing article comments, see Hiding article comments using
Curlybars.
