Toggle for POST requests (instead of GET requests)

Both DuckDuckGo and Startpage allow users to choose that the search engine employ POST requests, which do not include the query in the URL (and thus it is not included in browser history), versus GET requests, which show the search query in the URL (and on the browser tab). I’m really liking Brave search, and I think Discussions and Goggles are great features. But as a privacy search engine, it ought to have a setting for using the POST request method. Please implement this.
