Apologies for the delay.
I was able to turn off absolute accuracy by setting the variable $ABS_ACCUR to FALSE in the $option.dat file. This can be found in the KRC\STEU\Mada folder. In order to overwrite the variable it was necessary to hook up a mouse to the robot controller in order to minimize the HMI and work on the windows side. From there it is a matter of searching for the $option.dat file, changing the variable to false, saving the change and rebooting the controller. This file is write protected so it was not possible to change the variable through the Kuka HMI controls.
This screenshot shows the variables location in the file. This image was taken on my laptop, not the robot controller.
