AI role-playing their faction affinity, so unless they are Cravers, Hissho or have shit-ton of resources, they aren't aggressive for the sake of being aggresive.

This isn't a bad thing, as there are many ways to win the game, and other factions are better at that.

If I turn off victory conditions then their role playing will become useless, in which case the AI needs to adjust itself to military only, but does it?

craver style aggressiveness and conquest is universal and a paravan to any victory they like, not an obstacle.

Not really, as they are only a threat early on, but fall off quickly once you tank them long enough. Then they devour their planets and their FIDS production drops off dramatically.

Every faction is good at some things and not so good at others. So when you disable certain victory conditions, but leave factions suitable for them in, I don't know why do you expect different outcome. This isn't about adjusting play style (AI does so to a degree), it's about putting AI into unfavorable for it conditions.

If you want focus on elimination, play ES1, there AI just seeks an excuse to start the war, regardless of the faction.

If you want aggressiveness in ES2, rise difficulty further from hard. Any AI will be more prone to behave aggressively, as it'll have more resources in its disposal.

"disabling victory conditions puts the AI in unfavorable condition" you say.

therefore if the only victory condition set is score and domination then the AI should be aggressive and focus on military because it's the only way to win in such setup.

higher difficulty will work but the AI will pursue it's goals regardless that don't matter if victory conditions are off.

I would like to know whether the AI adjusts it self according to victory conditions?

Sorta? AI's motivation to pursue specific victory condition increases, as it gets closer to it, but before that it deems all conditions, aside of score, to not be feasible for the moment. So if you disable all of them, motivation to get them will never be above zero.

That said, to create truly all-aggressive AI regardles of the faction, you have to mod it. To my knowledge, elimination isn't a specific condition AI is aware of. Default AI just doesn't work like that.
