Hello, @beerbefore
1. Via FTP. The latest plugin archive you can find here https://www.8theme.com/download-plugins/ All the premium plugins in our theme are bundled plugins and don’t have autoupdate https://help.market.envato.com/hc/en-us/articles/213762463-Bundled-Plugins
2. Plugin does not allow this. So, just press the x button.
Regards
