Default [Q] Disable Fast Dormancy

Hi guys recently in mi city here in Mexico the Fast Dormancy doesn't work properly, if the provider doesn't have Fast Dormancy this comes to a terrible battery drain and i'm experimenting that, but i tried to disable Fast dormancy but I can't in my moto g, I disable only in my galaxy ace but I dont know how to disable in moto G and i was wondering if anyone here knows how to disable it.

Thanks
