We keep calling it a "derived neutral" mostly because nobody really knows what to call it.
It is really just an ungrounded conductor that depending on conditions may be operating near ground voltage.
If you want the conductor in question grounded - it needs be supplied by the main source grounded conductor, or come from a separately derived system where it is permitted - maybe required - to be grounded, but if separately derived you are not in parallel with the source winding like you would be with an autotransformer if you grounded the conductor in question.
