I'm pretty sure that answer to that question would be no. For numerous reasons. Things like time latency between such a command and the on-board systems response, the possibility of another "signal" or "unauhorized command" being sent by another entity (maybe this is what you are thinking about), but mainly because there are points in time where no radio transmission could be sent/received anyway because the plasma blackout. No "remote control" that I know of.
The plasma blackout will also likely make it difficult or impossible to receive data that is usually downlinked that might point to the point of failure.
Seems to me that the chase plane video may be helpful if they have good images.
