I’m surprised this wasn’t discovered earlier.
Don Yates will run to the shrine to pray when he’s all alone without any guards to protect him. Looks to be triggered similarly to how lockdown>panic works on Alma.

And while we’re at it with the shrine, Mr. Venom on Reddit discovered that you can use the shrine as an exit.
The way to use the shrine exit is simple, wear the Requiem Suit. It works for the mission and contracts.
The shrine exit could be a nod to the shrine in the Requiem mission in Blood Money, as noted here by Cake Things About Hitman You Just Found Out - #1543 by cake941
