[Closed] Respect System Units in Files Question

I need to know how to turn off or turn on this option by script.

I have been looking trough the reference but I cant find nothing about this.

The problem is I want to import some custom controls with “mergeFile”, in to a autorigg I am developing, but I scale them depending on the size of the character, but if this option is turned on and the files have different system Units setup, they will scale wrong, unless I turn off this option. I have tought of work arrounds but the easiest way would be to turn off this option “Respect System Units in Files” from the script and then turn it on or off depending on what the user had before.
I hope I make myself Clear.
An thanks for your help
