Force DNS

Is there a way to use some microcontroller (esp32 for me) as a WIFI extender, and essentially force a specific dns for every device that connects to the microcontroller? I know its possible to use it as an extender, that's where the question came from.

For example:

So the esp32 connects to a network and creates its own network to extend it. Then lets say my laptop connects to the esp32 and tries to use dns server 1.2.3.4, but the esp32 takes that and forces it to be dns server 5.6.7.8. Would that work or be possible? Am I even talking about dns correctly? is this even the right subreddit for this kind of question?
