Is there a similar "Autn" method that can only turn white and black automatically?

I know the method of automatic light and shadow: Trydesc1.putBoolean (charIDToTypeID ("AuTn"), true).
Now I need a separate automatic white and automatic black method, because I only need these two parameter values, and these two separate automatic results are not the same as fully automatic results, in CameraRaw you can press and hold Shift to achieve automatic, and I need to use jsx code to achieve automatic operation, is there a similar "AuTn" method that can automatically white and automatic black? Thank you very much.
