This is totally an enterprise feature. I have read enough enterprise documentation to know that. For example All of the wording talking about who is going to use this is "Admins", "organizations" and "end users". That is business/enterprise 101 talk right there.
If it is even available on the home versions it is going to be off by default as it requires a good bit of setup to turn on.
If Microsoft wanted to track you via DNS they would just do the same thing that Google and Apple are doing with their phones. Have a secure DNS option that is on by default. That uses DoH amd happens to use their DNS servers.
Also Microsoft doesn't need DNS to track anyone in Windows. As they control the OS.
