Yes - there should.  I dunno what it is tho :(   All I've come up with
is running my own resolver & blocking DNS traffic from TVs etc. to the
outside world.

I just saw a msg on the dns-ops mailing list about DNS privacy - this
is a good read:
https://blog.powerdns.com/2019/02/07/the-big-dns-privacy-debate-at-fosdem/

and if you use firefox
https://hacks.mozilla.org/2018/05/a-cartoon-intro-to-dns-over-https/

tl,dr: maybe someday soon firefox will ignore your dns blocking & go
straight to a cloud provider with encrypted dns requests.
