Intel Rapid Storage Technology is not compatible with Bypass IO and Direct Storage

[lm90]

After installing RST version 17.11.0.1000 my system loses compatibility with direct storage.

The compatibility can be checked using the following command in cmd :  

fsutil bypassIo state c:\

More documentation here:

https://learn.microsoft.com/en-us/windows-hardware/drivers/ifs/bypassio

The Intel RST driver is reported as incompatible whereas the standard Microsoft driver "Standard NVM Express Controller" works and is reported as  compatible.

Installing RST replaces the "Standard NVM Express Controller" driver and makes direct storage unusable.

The system is currently running in AHCI mode.

I would like to know if this behavior is intended and if support for Direct Storage will be added.

My system:

Intel i7 7820X

MSI X299 SLI PLUS

1 M.2 PCI-E SSD, 1 SATA SSD, 2 HDDs.

Windows 11 22621.2361
