Although you can’t enable/disable a chat as a part of Zoom’s scheduling options, you can permanently disable Zoom chats. 1. To do this, open your preferred browser and sign in to your Zoom account. 2. Then, go to Settings and select the Personal category in the bar to the left. 3. Select In Meeting (Basic). You’ll see the Chat toggle switch, flip the switch off. You can also disable the Private chat option and disallow the participants to save the chat.
