How to set color management view transform for cycles stand-alone

How to set color management view transform for cycles stand-alone ?

current I test cycles standalone ,it’s powerful ,but it’s default use standard view transform in color management,

here what I want to ask how to change view transform from standard to filmc?

I search every codes and can’t find any interfaces and function to do that .

thanks .

here is my xml
