remove_dependency(target) method in PBXNativeTarget

My PBXNativeTarget has some dependencies which are not being used in that target, so I just need to remove them via Xcodeproj. After digging into the code I see that there is a way to add target dependency on the target by using

`my_target.add_dependency(custom_target)`
But i don't see any method like `my_target.remove_dependency(custom_target)`

Is there a way I can remove a given dependency from that particular target and not from the whole project because there might be other targets that might be consuming the above custom_target.

Thank You.
