Does OpenXR have "OS Splash Screens"

The oculus documentation mentions configuring an OS Splash Screen in the project settings, but the OpenXR plugin does not seem to have anything equiavalent in its documentation and only shows blueprint. If I use the blueprint nodes I'm worried it will not pass the store's 4 second test as mentioned in the oculus documenation.
