Flatpak uses remote repositories (usually just called “remotes”) in order to search for and download software. If at any point you decide that you no longer wish to download applications that come from a particular repository, you can always remove it from Flatpak. This will prevent Flatpak from querying the specified repo for future software searches and updates.
