How to use SubobjectInstantiationExclusionList in UE 5.1

Hi!I am reading the Unreal Engine code in Class.h and finding the function AddPropertyToSubobjectExclusionList() is not using.
Seems like the function can let us disable some subobject when we are creating a new actor.
So if someone can tell the way to use these function It will be a great help for me.
Thanks.
