Feature For Routing Request To Another Address For Blocked Websites

Hey, I've been searching a lot on how can I disable Google chrome's Default DNS(i.e. the DNS it uses when it bypasses user provided DNS) but it seems like there no such way discovered so far. so during me research on this topic I've found out that google actually sends requests to its DNS when the user set DNS do not responds with an address. So I was thinking that if there would be a feature that can route the request to another address for block sites so Google's DNS won't come into the picture.

just a thought idk how much effective will it be.
