Problem with drivers for Microsoft Surface - State: not required. CB 1802

I have followed the steps to get the drivers into WSUS and SCCM.
The problem seems to reside on the clients, detecting that the update is not required (not installed or needed).

I tried joining the shipped image (the one that came with the device) to the domain, with mimimal GPO, and still have this problem.

I verified these settings that were NOT enabled on my workstations:

• Prevent installation of devices not described by other policy settings

• https://www.howtogeek.com/302595/how-to-stop-windows-10-from-automatically-updating-hardware-drivers/
  Do not include drivers with Windows Updates
• SearchOrderConfig reg for drivers
  • Go to Run –> regedit
  • Go to: HKEY_LOCAL_MACHINE –> SOFTWARE –> Microsoft –> Windows –> CurrentVersion –> DriverSearching
  • Change the value of “SearchOrderConfig” to 0.

Only thing of note I found was in the windows update logs [ps get-windowsupdatelogs]. Multiple entries of the first and one entry of the second. Attached log for review (changed from .log to .csv to allow upload). I haven't been able to find out much on these entries.

Clients are running windows 10 Pro 1703 or 1802.
SCCM CB 1710, then upgraded to 1802 with hotfixes applied. Problem persisted.
