Hello. Thank you for contacting the Toolset support.
There is no such feature available to setup such dependent filter using the product category.
The workaround Would be to create a page A where you display the top level category with taxonomy view X and when you select any Available option from those terms (images) you should show the child terms on page B using the taxonomy view B. That means you will have to create separate page to display top level terms as well as child terms.
