Is there any way to do camera shake using ork or is it just a unity thing

There's a Camera Shake node in Schematics if you're using default camera system.

The Shake Camera node can do that.

Like most other camera/movement nodes (except for the nodes specific for player/camera controls) they work independent of using the built-in controls or custom controls.
Though, you should have camera controls blocked while using them, as otherwise the active control will usually overrule any position/rotation changes being made.
