If your Chromebook supports Google Assistant, chances are that you got it enabled while setting up your device. Now, what if you want to disable Google Assistant?
Let me show you how.
Open the Settings app. From the left pane, select “Search and Assistant“.
Click Google Assistant.
Click “On” to toggle it to “Off“
Google Assistant is now disabled on your device. You can always come back to Settings > Search and Assistant > Google Assistant to enable it again.
