To "override all [of something]" means to prevail over or dominate the whole or all of something. In terms of technology, it means to manually take over. Ex: We had to override the system and land the plane manually. Ex: The decision I make will override all the ones Ryan made since I'm above him in authority. Ex: I'm going to override the storage for this project with the video. Ex: Sometimes, doctors override the wishes of their patients.
