If you've already gone down this path, just block it on your wifi hotspot/etc. I've got a pile of ways I block things, from wifi blocking, nameserver blocking, to full blown firewall rules blocking IP ranges.

Solves untold grief too, no longer do my windows machines update on their schedule, they don't report usage metrics to MS/etc. Same with my LG tv, it doesn't get to talk to LG services except when I allow it (which is rarely). It just has some generic LG backsplash on the left hand side where it has in the past wanted to display ad's (although they backed off it at one point, but by then it was too late and lost its privileges.

My current monitor is a 4K TCL Roku TV, but it's only connection is an HDMI cable to the PCs video card.
