Unreal Compile Error - OVR + XR_Foveation

Today I was testing some optimization settings and ran into this error while compiling UE5.4 project, 
MetaXR plugin v67

LogOVRPlugin: Display: OVRPlugin 1.99.0 ... initialized
LogOVRPlugin: Error: CreateFoveationProfile() failed: required extensions not enabled: XR_FB_foveation 0 (arvr\projects\integrations\OVRPlugin\Src\Util\CompositorOpenXR.cpp:11158)

its related to this setting:

this is called in my game instance on init,
removing that allows for successful compile,

what am I missing?
Plugin - OpenXR = Enabled
Plugin - MetaXR = Enabled
Plugin - MetaXR Platform = Enabled
