Disable update notifications?

This night, at 04:37, there was a notification that my Homey could be updated.
Because I made a flow to monitor my sleepwalking child, I had made sure that all Homey notifications could pass through and would sound loud, so this woke me up.

Is there a way to turn off notifications for updates and only have notifications from my flows?
Other suggestions to be woken up at night from a flow, other than buying a siren or new spotify device? I tried IFTTT, but could not get it to work reliably.

Yes, if you go to setup, System, Timeline you can set up the notifications.
