In the latest versions of Yoast, the setting already includes the functionality to remove comments and other elements from the header.

Where is the setting exactly? Remove powered by HTTP header option under Crawl optimization doesn't remove this.

I'm on Yoast 24.8.1

Sorry, I was wrong 😞 — there’s no option to remove comments, but I could swear it was there at some point 🤔. Now I’m left with doubts. I use Autoptimize and WP Super Cache; they remove all comments, including the “Powered by Yoast” one. Cheers.
