Hello, guys!
 Thanks in advance, I need some help. I have a cc3+ Character and he has only four fingers, but normally cc3+ has five fingers. So, the point is that I need to disable the fiveth bone, but it doesn't not show the options in CC4.
I select the bone, but there's no way, also I can't use weight paint, cause is not available for cc3+ characters, only for theirs accessories. I also tried blender pipeline to clean the weight, but when I bring back  into CC4 , it applies the weight back automaticly to the bone. 
What I could do, some tips or turnaround?
