Silent auto update

[1Rab]

Hi all, hope someone can help please.

I am testing a deployment of the Zoom client using SCCM to deploy and GPO to control updates etc. 

My install command is:  "msiexec /i ZoomInstallerFull.msi /norestart MSIRESTARTMANAGERCONTROL="Disable" /L C:\Temp\ZoomInst.log"

I have enabled GPO settings under Computer config policy:

AU2_EnableAutoUpdate

1

AU2_SetUpdateChannel

1

I need Zoom to auto update when no one is logged in, but it never does.

I can get it to update when a user tries to launch, but would prefer it done during the night on a maintenance period. 

Is this possible?

Thanks for any pointers.
