Remove annoying features from LG TV

Kinda useful and kinda useless gist i've made?

Removing Microsoft Copilot

Maybe it won't work, but modify the appinfo.json of copilot app and change from "removable":false, to "removable":true,, and going to home and uninstall it. Before uninstalling, it requires reboot to take effect and deleting copilot. Might say something like Permission denied or it changes from true to false. Needs root access though. Bind mount might help.

Remove software update alert

You can go to Homebrew Channel, and into the settings, and enable Block system updates, and reboot. This only works if your TV is rooted.
