I've since received information of a workaround - listed in a different thread:
Try the following to enable updates:
1) Navigate to C:\Program Files (x86)\Common Files\Adobe\AAMUpdaterInventory\1.0 and you will find a .dat file ( AdobeUpdaterAdminPrefs.dat).
2) Please open the file in question and you will find a line item : <Suppressed>1</Suppressed> .
3) Please change the Value from 1 to 0 and save the file back in the same location.
On a Mac, essentially the same, however location: /Library/Application Support/Adobe/AAMUpdaterInventory/1.0/AdobeUpdaterAdminPrefs.dat
I was given further advice that DPS toolkit updates are not available when you create the deployment package from Adobe Application Manager Enterprise Edition on Mac OS. (I believe this may be the same using Creative Cloud Packager as you've found)
Deployment DPS Toolkit Update| AAMEE |Mac OS
The above article suggests that you can download and install the DPS update silently, however, an end user must be logged into computer - not really feasible for enterprise environments.
So I guess the process for this would be:
1)Copy the contents of the DPS update package to remote machine
2)Enable updates by modifying the AdobeUpdaterAdminPrefs.dat file
3)Remotely launch the DPS update silently (when someone is logged onto machine)
4)Disable updates again when complete...
