No, DD is literally an option at the moment you create your USB bootable key within Rufus.
If you don’t see the DD option for the copy in Rufus, either because you don’t find it or because it is removed now, then don’t waste your time use Ventoy.
Also this one (Suse Image Writer) works great, drop the iso, select your USB and go 
//EDIT: also I found this DD mode gone in version 3? · Issue #1148 · pbatard/rufus · GitHub
