I’m going to assume you’re looking for a solution in a personal context, not organizational so I won’t suggest local group policy.
Instead, I’d recommend removing the msstore source from “Winget”. The Microsoft Store uses this source to push updated for installed third party applications. It may not solve the issue entirely, but I find that as Microsoft expands the use of winget as a package manager for Windows (especially Windows 11), the store itself seems to use it for update provisioning.
“Community Add-ons” leads me to think this is probably Kodi. You can generally do IPTV streaming through it, or torrent streaming even.
