Hello,
Welcome to Microsoft Q&A!
You could try to use UIElement.ProtectedCursor Property.
You need to subclass the UI element that you want the cursor to be changed in, and then add a method that sets a ProtectedCursor property.
For more details you could refer to the thread: https://github.com/microsoft/WindowsAppSDK/discussions/1816
Thank you.
