Wouldn't a simple switch stop this from doing its job. Place the switch
inline with the Scart cable to the TV so you can switch off the signal (by
grounding pin 8 on the TV side, when you go to bed and the TV will never
receive its wakeup call.

Perhaps have the switch link pin 8 to pin 17 to disable the signal and
back to pin 8 to restore it.

Its a very low tech, temporary solution to your problem.
