Get only direct interface instead of all?

I have a class like the below. GetInterfaces() says

If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the interface constraints and any interfaces inherited from class or interface constraints.

Is it possible for me to not get any inherited interface? When i use GetInterfaces on ABC i only want to see DEF, not DEF and GHI.

interface DEF : GHI {...}
class ABC : DEF {...}
