CC/DLC for better AI allies?

I'm trying out eu4 after hundreds of hours in ck3 and hoi4. I'm getting migraines from my allies' 20k strong deathstack standing still and watching me in the tile next to them getting massacred by a battle that we could have won had they reinforced. is there some sort of dlc I can buy or mod I can download that makes ai allies more aggressive/smarter? or that adds some sort of system where I can give them commands like subjects?

ck3 ai allies are bad but at least their troops mostly follow the player's army around and thats easy to deal with because its predictable. I feel like eu4 allies take this imbecility to a whole new level and actually try to intentionally sabotage my war. it's making the otherwise cool game feel really unplayable at times
