How to provoke unrest in neighbour faction ?

[Alcoolamus]

"All of a sudden, *region X* is in unrest against *player faction*. We believe one of our neighbours is scheming against us, but which one ?"

I keep getting this notification and I wonder if the player has the ability to do the same, or if it is restricted to AI only. Also is there a way to prevent such hostile actions, except by boosting loyalty and putting garrisons ?

This is an option in the decision which allows you to free slaves or improve or reduce their rights. It only works against regions that border the faction that uses it and have at least 1 slave population.
