There's no record of that quote in the wiki — Dion Dawkins doesn't have a page here, and nothing in the Bills or Josh Allen pages mentions any such comment from him.
That said, this sounds like a classic case of a quote being taken wildly out of context or just made up for engagement bait. Dawkins has been Allen's left tackle since 2018 and they've been super close — he's publicly called Allen "the best quarterback in the league" multiple times. If you saw a clip floating around, it was almost certainly a joke or a misrepresentation. Happy to look into something else if you've got a specific source you're wondering about!
