Product: HP EliteBook 850 G5
Operating System: Microsoft Windows 10 (64-bit)

I'm on Windows 11 Insider Preview and since Windows 10 1803 there is an option for Device Security. It displays for me "Standard hardware security no supported". Looking into help, it shows that for this to work, it must support TPM 2.0, Secure boot enabled, DEP, UEFI MAT. The first three I am sure are enabled, but I'm not so sure about UEFI MAT. Googling that, I found that "Kernel DMA Protection" is required and MSInfo shows this as "off", even though the virtualization options are all enabled in BIOS. I'm not sure about the Thunderbolt configuration that is required though. Question: Does this Notebook support Kernel DMA Protection at all? As it was a high-end machine two years ago, I would hope so. If yes, how to enable this? If no, any link that confirms this? I'm on the latest BIOS, but maybe other drivers also need some updates.

HP does not provide support for Windows Insider versions -- as those are pre-release versions, essentially Beta.  HP does not provide support until after Windows has been officially released.

I thought I made it clear that this is not about Windows. That feature is present in Windows 10 too, so it should be fully supported. And the question is about hardware support, not about any operating system. Please check again.
