Disable News Feeds in Google Launcher
Android 9, Pixel 2

You can disable the Discover feature (the one that shows news items on the left-most screen of the launcher) by:


Go to that screen
Select three dots on that screen on the top right
Choose "Settings"
Under "Search", choose "Discover"
Turn off "Discover: see stories related to your interests on the home tab of the app"


Note that this turns off all info on that page, eg weather.
