Partners can choose to disable all types/placements of ads ("skippable video ads", "non-skippable video ads", "pre-roll ads", "mid-roll ads", and "post-roll ads") except for "display ads" (that is, banner ads). As for whether those options actually work, I can only assume so, but the article you linked is specifically about non-partners.
