If you are asking if it is possible to change the direction the operator stands, operating the steer tiller with the right hand and the function handle with the left hand, then no there is no option for that.
If you want to switch the direction the wheel turns when turning the tiller clockwise or counter-clockwise there is:
You need to swap hoses B and C of the steering torque converter under the steer tiller.
You can also swap the hoses at the actual steering unit above the steer tires, I personally just prefer to swap the hoses at the torque converter but either option will work.
I attached a photo of the hydraulic schematics for reference if needed.
