Bundled plugin’s license

Bundled plugins do not come with a license and do not require activation or registration to use them with the theme. Please read more about it on Envato help center

The license notifications can disable from The7 > My The7 > Silence bundled plugins notification.

All bundled plugins can update via The7 > Plugins.

However, if you need to access their premium templates, addons, support from plugin author, and direct updates, you can buy a sperate license for the plugins and register it.
IN such a case, you will have to delete the bundled version and then install the standalone version.
