Blocking duckduckgo from misbehaving

Here is a genuine “bug”
Brave hasn’t a way of blocking duckduck from misbehaving.
Try to use “ search engine” with “Brave browser” to see how duckduck preempts its use.
Then please instruct me how I might block duckduck from taking command over my Brave install, disallowing my free choice.
