Memory Integrity option cannot be turned off

I am unable to turn off the Memory Integrity option for some reason.
I even followed the steps below and rebooted, still keeps on enabling itself.
Turn On or Off Core Isolation Memory Integrity in Windows 10

Even try these settings to disable Credential Guard here.

Even reinstalled Windows 10 by wiping out all the partitions starting from scratch. Still no luck.
Think this is a bug in v1809.

Before the complete reinstallation, I did enable the VBS settings with UEFI Lock features under the Group Policy.
But I am stumped as to why even after a reinstall I cannot disable the Memory Integrity option.

Any help would be greatly appreciated.

Thanks
