Engine Knock, Vacuum Pump?

This is a 2013 FRS Automatic, 103k miles. My engine is currently making a tapping/knocking sound, the sound is not there when the car is cold; however, when warmed up the sound is heard. My biggest fear was engine knock but after browsing other forum posts I've seen that the automatic transmissions have an issue with vacuum pumps that sounds similar. I have attached videos of the sound below, it is primarily heard on the passenger side of the vehicle. What does this sound like? Engine Knock, Vacuum Pump, or other?

Sounds like a bad vacuum pump (+ you stating the sound is not present when cold):
