An easy way to do that now is to open the spindle door. That secures power to the VFD, or at least it does on the 770 and 1100. I don't have a 440 wiring diagram (can't believe Tormach still hasn't published that manual electronically) to check.
I don't see the "un-commanded spindle engagement" in the bug list on the path pilot website. I recommend you submit it to their bug tracking list.

I would also recommend you phone them and tell them, since this is a huge liability issue.
