Extremely unlikely, with a properly designed, maintained, and controlled firearm. A worn out machine pistol knockoff can have a sear that consistently drops out when struck in the right spot. There’s a continuum there, and a strict enough reading of ‘explicit command from a human operator’ would be that anything that can be fired accidentally crosses the line.
For that matter, runaway is a common enough occurrence in belt-fed firearms that learning how to minimize the effects is part of learning to use the weapon. (Heat in the chamber is enough to cause the powder to ignite without the primer being struck by the pin; the weapon continues to fire until it runs out of ammunition.)
