Need option to disable checking of updates

I use keybase once in a while so the frequency of updates annoy me. If there is a way to turn off update till the next time I decide to use the application or a notification to update the application when I start the application, it would be much better.

No file, test, or entry point is named in the issue. Start by locating the client's update-checking flow and determine how update checks and startup notifications are currently handled. Done means users can suppress recurring update checks and receive an update notification when they next start the application.
