Be careful because on second generation Firesticks (Fire TV 4K MAX) the commands that allow you to change the DNS completely block your internet connection on all your connections.

I have pihole in my network, so it blocks most of it without setting any private dns. But sometimes it bypasses pihole by using the hardcoded 8.8.8.8 DNS. I blocked 8.8.8.8 using a NAT rule on my router and now it's using pihole properly.

The same way you can set NextDNS as the dns on your router and add a NAT rule to block the 8.8.8.8 IP.

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

You can't, you will need root for that.
