You can see all the exposed properties for controlling how the camera is controlled through user input here: https://cesium.com/docs/cesiumjs-ref-doc/ScreenSpaceCameraController.html?classFilter=ScreenSpace. You may need to disable the default controls and implement your own if the options you want are not exposed in that class.
