Why do you want to not disable it I would say. Having DNS over HTTPS not only completely breaks local name resolution (e.g. http://fileserver) and you must manually specify IP addresses in the browser to connect to local hosts, but also if you already have (like I have on my LAN) a local DNS server that does DNS over TLS is useless and also you don't benefit from for example query filtration (I filter out ad servers and trackers from DNS requests)
