[Blade Runner 2049] Nexus-9 models are known for obedience. How was K able to go against his orders?

He was obedient, but he’s still intelligent, sentient. 

Give a sentient person reasonable cause to believe their entire life is a lie, and they they aren’t actually a replicant but a human being, and they are capable of exceeding their programming. 

In short, K had such an intense existential Android crisis that it overrode whatever his baseline programming was. His baseline tests he gets at the police station show he is capable of going “off mission” because otherwise they wouldn’t test for it.
