Not sure if this is what you are looking for but I believe under the Agent Policy there is an option:
"Reboot options after product deployment (Windows only):"
with two options
"Prompt user when a reboot is required "
"Force automatic reboot after (seconds): XX"
No, it will not ask for reboot.
That is what I am looking for. I knew it was the somewhere. I will see if it works for me thanks......
