Hardware watchdog in Device OS 5.3.0

I was not able to see the hardware watchdog is being stopped during sleep on the B402 in my experiments. Is it possible for it to stop on B402? It doesn’t look to be possible to stop the hardware watchdog at the application level, so is there some additional control available at the device os level?

I made a previous post with some example code here:
