NEW Deployment Deadline Behavior via Powershell?

[KchInfoSystems]

On the deployment properties screen, User Experience tab, there's a pair of checkboxes beneath the "Deadline behavior" header. I'm trying to access them via Powershell.
We have several software update deployments (OS patches) that are poorly defined and so are not fully respecting maintenance windows.
I need to identify & fix those deployments.

So far, I can:

• Collect the deployments via Get-CMDeployment
• Identify Software Updates vs Applications, et al via FeatureType
• Identify Required vs Available deployments via DeploymentIntent
• Get the details of the OS patches via Get-CMSoftwareUpdateDeployment
• Using that data, I have probably identified data matching several checkboxes on that dialog page
  Including one of the two critical checkboxes: RebootOutsideOfServiceWindows

But I cannot find the data element matching the "Software updates installation" checkbox, which is, of course, the one we have wrong the most .



Any clues? It could just be a non-intuitive name, but I don't think so -- I changed one deployment & took data snapshots before and after the change, but I see no differences in the objects I have. :-(

This is the data from Get-CMSoftwareUpdateDeployment:
