What if I want to make the dns read-only , I mean such that it can't be changed from mobile at least

I ran those ADB commands on the Fire Stick 4K Max 2nd Gen and it worked for about a month and a half. But now I'm having problems with the Internet connection: when I start it up, I get a “No Internet connection” warning and there's no way to get it to work (I've already tried restarting both the router and the Fire Stick). The only way to fix it is to disable private DNS with the command “settings put global private_dns_mode off.” Is anyone else experiencing the same problem and has found a solution?

Additional information: I use NextDNS, but the problem also occurs with other DNS servers.
