Overriding the built-in filtering of the TreeList will require overriding the internal methods. What is the scenario you are facing? Having more information will help me better understand the case and allow me to advice further.
i need to have filter the tree for the field eq "X" or field is empty, now if I create such filter descriptors, it works wrong, having a tree I would like to filter out any children if parent eq EX and despite having empty items down, seems to make it, I need to create my custom filter logic, that is why I asked about ability to override existing dataset filter method

If you are using local data you can use a function to customize the filter logic:
