PIT Mutation Testing maven plugin skip private methods

I believe that not all private methods should be tested as independent parts of code. That is why I want to exclude them from pit-reports of PIT testing tool maven plugin. I tried to find a way of doing this, but failed. Some close configuration described here documentation at excludedMethods topic, but it's obviously not the proper way of excluding each private method.

So my question is where a way to exclude all private methods from analyzing by PIT ?
