Rotation is an available property on Qt for MCUs v1.9, however our docs do not clearly indicate the limitations for this property (https://doc.qt.io/QtForMCUs/qml-qtquick-rotation.html)
In QDS v2.2 - MCU build, the rotation property on an Item is disabled on the property sheet but I can add the rotation value on the Item within the text editor, without error. This also allows me to alias the rotation on the component and set variable values on each instance.
Since there are no errors when I build/play in QDS I assume this will have no issue. However after internal discussion it was mentioned "Using rotation with anything else will likely cause errors during compilation in QtC."
