I don't know why you're downvoted, because that is a very good question. What you have to do is add an entry in your local nameserver for domain use-application-dns.net and set it to NXDOMAIN. See https://support.mozilla.org/en-US/kb/configuring-networks-disable-dns-over-https https://support.mozilla.org/en-US/kb/configuring-networks-di.... Hopefully Google will use the same method for disabling DoH in Chrome. But I won't be surprised if they're going to force DoH even harder, and make it even more difficult to turn off.
