You can disable tracking account-wide at https://myaccount.google.com/data-and-privacy https://myaccount.google.com/data-and-privacy - scroll down to the confusingly-named "History settings". If you turn these off, particularly "Web & app history", your TV (and all other Google devices) will obey the settings if it is logged into that Google account. It will still be contacting Google's servers, but it won't be recording anything.
