The way I deal with applications that do this is to use my router to ensure that all DNS requests go to the server I want (in my case, my own DNS server, but it can be any you prefer). That's an incomplete solution because it doesn't help with DoH or with applications that don't use the standard DNS port, but it catches most things. I have a separate solution to intercept DoH requests, but that's a whole lot more involved.
