Trigger alarm if pilot is already killed/unconscious

Can the guards of the enemy spaceship still trigger the alarm if the pilot is already dead or unconscious?

This matters especially for the "Silence Clause" missions, after those missions you get a bonus when no alarm was triggered.

No, that doesn't count as a silenced alarm.

I've tested this myself in game today; letting the enemy alert; and even toss me off the ship while the captain was dead. I still received the bonus.

Without the pilot, the alarms on ships no longer work.

Here are some images to show this:

You can see I kill the pilot, get noticed; but it doesn't count as an alarm because there is no way for it to trigger. I get the silent award.
