to have an option to remove them from getting points

They are already in the config.  Try setting these to zero:

    "chainsaw": 0.0,

    "jackhammer": 0.0,

Or did you mean from mining and logging?  Honestly as long as they finish the tree or node that is what the reward is trying to provide an incentive for.  If you remove that they may not finish them to avoid the risk of visibility of a tree fall or node disappearing (in PVP).

Can you explain to me you want this functionality?
