Voltage scaling on Arduino Due

Is Dynamic Voltage Scaling (DVS) or Dynamic Voltage and Frequency Scaling (DVFS) is supported on Arduino Due?

It apprears that SAM3x microcontroller has a core voltage ranges from 1.6 to 1.9, so technically it would be possible. Does Arduino provide any means to utilize this freature?

Your code runs in supervisor mode, you can do anything the chip allows I think, including
getting it horribly wrong!
