In Device Manager, you can schedule updates for a headset or group of headsets by creating blockout times when you don't want the devices to be updated.
To schedule updates:
From Device Manager, click on Device Fleet.
Click the headset or group of headsets you want to schedule updates for, then click Settings.
Click
next to Operating System Updates, then select Blockout Times.
Select the dates and times when you want to avoid updates.
Click Save.
Bear in mind that these updates will take place after your headset has been asleep for at least one hour. Your devices should be charged or connected to a charger and connected to Wi-Fi. If your device isn't connected to Wi-Fi, the update will not take place.
