Is the aircraft not fitted with some sort of alarm that sounds after a pre-set time if no control inputs (including key presses) are detected? With this flight operated by a 787-9 I am even more surprised if that is not the case.
You mean the 'Pilot Response' EICAS message that sets off the Master Warning chime if no transmit or MCP button is pressed, pulled, twisted or rotated?
The company sets the time limit and it's active when the aircraft is Clean, above 20,000ft and in the cruise.
Never catch on!
