HyperPixel 4 Touch - how to rotate

How do I rotate the HyperPixel 4 Touch?
I managed to get the display to landscape, but then spent ages trying to get touch to work before I found posts saying that rotate does not work for the touch sensor.

The instructions Getting Started with HyperPixel 4.0 say to use options that no longer exists on the desktop.

Also is it possible to do it via terminal?

Thanks
