I am not sure if this belongs on serverfault or superuser.

I would like to override SetThreadExecutionState(ES_DISPLAY_REQUIRED) to be a no-op. How is this accomplished?

Is there some registry setting that can be altered instead of API hooking?

Blocking ES_DISPLAY_REQUIRED will prevent apps from keeping the monitor powered on. I have an application (likely the antivirus) that is preventing some monitors from entering power-save and I think this function is the culprit.
