Cannot enable Defender Performance Mode for Dev Drives

[alexanderdk]

I'm running up to date Defender on Windows 11 Pro but cannot enable Performance mode for Dev Drives.

The Configure performance mode status GPO does not exist at all so I ran:

set-MpPreference -PerformanceModeStatus Enabled

which did not report any errors, however the Dev Drive Protection section in Virus & threat Protection settings > Manage settings is completely missing.

Am I missing something to enable this facility?

I have the same problem.

@Performance mode works only in Dev Channel Windows (aka preview).

May be someone know when performance mode will be available on ordinary Windows version, not only in Preview?
