Property specifier for "Editable when Inherited"

For a USkeletalMesh variable, what’s the C++ equivalent of this?

e.g., what do I need to set inside the UPROPERTY?

UPROPERTY(EditDefaultsOnly, Category = "Default")
USkeletalMeshComponent* MeshFPP;

Hello! This is bEditableWhenInherited prop of UActorComponent
