Can't make this request in Eloquent?

Question

Laravel

Good afternoon! I googled something, searched, but as a result did not find the necessary method for building a query identical to Sql.

SELECT * FROM es_proxies WHERE es_proxies.proxy NOT IN (SELECT proxy FROM es_proxy_useds)

If you use table, then it turns out that you can take one table. With joins, such a request could not be cranked out. With DB::raw it didn’t work out either, but how can you actually do this then?
