Windows 10: unable to turn on Memory Integrity

A few days back my system threw up a BSOD for Reference by pointer and after that Windows security is unable to turn memory Integrity on due to some incompatible drivers namely SoliosGigeNic.sys, ConcordGX60.sys, and ConcordGX51.sys all by Matrox Electronic Systems.I tried everything I can, BIOS update, PC factory reset, Driver update, Display driver clean install and update, even uninstalling the third party Antivirus QuickHeal.I know the fault driver is NIC and I am unable to figure out whether this is really a software issue or hardware issue.PC specs:Alienware m15 R7 Laptop16 GB Ram, 1

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.
https://docs.microsoft.com/en-us/win...l-guard-manage

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

Can't turn on Memory Integrity due to INtel graphics drivers

On my Dell Optiplex 7010 Win 10 Pro 64-bit PC (version 20H2), I can't turn on Memory Integrity due to some Intel graphics drivers. I have Intel graphics, not a separate video card. See screenshot below. Any suggestions? Thanks.
