Jagadesh,
Based on the logs that you shared, looks like that SCCM is correctly discovering these machines:
Discovery to IP address 192.168.1.3 succeed. AMT status is 4.
*and*
Discovery to IP address 192.168.2.160 succeed. AMT status is 4
AMT status 4 means that is Externally Provisioned, i.e. Using Intel SCS in your case. What happens is that SCCM takes some time to refresh the status and in order to speed this process, you can force an "Update Collection Membership" following with a F5 (refresh).
For this discovery (i.e. SCCM native that shows in column), SCCM doesn't use the agent to update the status, it's done directly from OOB Service Point, connecting remotely to vPro machine, that is the reason that Inventory policy didn't make any change in this status.
Please, let me know if worked.
Best Regards!
