DataViewCtrl: is there a way to hide columns for children, similar to HasContainerColumns in DataViewModel for parents?

Hi ALL!

I'm playing with DataViewCtrl with custom DataViewModel 
<https://github.com/svn2github/wxPython/blob/master/trunk/demo/DVC_DataViewModel.py> example: 
a tree structure with several columns including checkboxes. There is HasContainerColumns 
<https://wxpython.org/Phoenix/docs/html/wx.dataview.DataViewModel.html#wx.dataview.DataViewModel.HasContainerColumns>method 
for DataViewModel which affects displaying the columns for parent nodes: 
all columns except the first one could be shown or hidden. 

Is there a similar method to control displaying the columns for children? 
I'm trying to get a tree where checkboxes are displayed on the parent level 
only, and the children's level has no checkboxes at all.

The farthest I could get by now is to define the children's level as 
sub-parent and disable displaying values in the columns. But no the items 
have the expand/collapse icon instead :(
