The ndc command used didn't work on my Nvidia Shield (rooted with a custom-built kernel). The ip link command does work. I have only tested this on an Nvidia Shield (Android TV - Version 9.0 Pie).
I couldn't find a lot of documentation on ndc so it's possible my device/kernel is misconfigured. If you suspect this is the case, let me know.
