I can't seem to find this info in FAQ's or knowledge bases. Figured a compatibility table or list would be an easy find.
OpenVPN itself does not really care about the DNS you are using. Basically the DNS is something that you set (manually or automatically) and they are used.
I presume mullvad is trying to inject their DNS, but you want to use something different. Then you can manually configure the cleanbrowsing DNS on your router, but you have to be sure that mullvad allows DNS traffic to other servers. If they block it, then you can't do much.
