How to make a "Camera Rig Manager" that turns off the other 5 cameras not in use?

Hello I am new to Unity and scripting and need some guidance.

_

I am currently trying to make a guided tour that allows to see how visual impaired sees the world.
It is actually impossible right now with this technology to simulate. But im am making the tour for a architect class and they will experience it through Oculus Go. Already made something and made it work. But I want to change how you navigate inside the spheres. And I see now that it would be nice with some more C# knowledge.
_

I using the [Unity Documentation][1] to make this, but get this error.
_
Assets/Scripts/SetActiveCameraRigA.cs(76,39): error CS1061: Type UnityEngine.GameObject' does not contain a definition for enabled’ and no extension method enabled' of type UnityEngine.GameObject’ could be found. Are you missing an assembly reference?
_
And i made a [Google Doc][2] to show with pictures and code.

_
Can anyone help me? I would be so happy for any pointers from anyone!

        CameraRigE_DiabeticRetinopathy.enabled = false;
        CameraRigF_MaculaDegeneration.enabled = true;
    }
}

change .enabled to SetActive(false) / SetActive(true)

example :
CameraRigF_MaculaDegeneration.SetActive(false);

Did some changes but still stuck. No Errors and Warnings this time.

Now the problem is to actually manage to switch between the different CameraRig’s.
