Is there a way by which we could control/move Cinemachine FreeLook Camera using TouchField/TouchInput for mobile?

This question is based upon the query raised in the thread: https://answers.unity.com/questions/1386147/how-to-move-cinemachine-freelook-camera-with-touch.html?

One great solution was provided by Jean-Fabre: http://answers.unity.com/answers/1486076/view.html

I added the script mentioned above, on my main camera! The touch input does make camera move on both X and Y axes. But, it overlays the UI Canvas components. I have a virtual Joystick, placed at Bottom Left Corner of Canvas, that is responsible for Player Movement! When I use use Joystick for movement, it also changes camera positions/angles/orientation, along with player movement.

Is there any way by which we could define a touch-field area, as in certain portion of screen where we can touch anywhere on screen, for camera rotation, instead of whole screen (for example: restrict some portion of screen, where Joystick is present, about 30%-40% screen on left hand side, and rest 60%-70% screen on right hand side, that could be used for rotating free-look camera)?

Hoping for a fruitful response!

Kind Regards!
