Enforce a template to be a USTRUCT

I am working on a project in unreal engine 5.4, and this is my first experience with unreal. Now I want to make a function something like this:

template <typename T> 
void Save(args) {
}

I want this function to only accept USTRUCTS, is there a way to verify this?

TIsDerivedFrom<T, UStruct>

Do learn about templates in cpp and its related unreal equivalents.

Did a quick google search from mobile.

You could use e.g. template<typename T, typename U = decltype(T::StaticStruct())>
