If that filter is a widget… you can use these two plugins to help achieve what you want (to have the widget NOT appear on the vendor store pages but still appear on the main marketplace pages):
After installed & activated, go to APPEARANCE > WIDGETS in your wp dashboard. You can add different widget logic to each widget to enable or prevent widgets showing on various pages.
example: If you have your vendor store pages as http://www.yourwebsite.com/VENDORS/a-vendor-shop then you would enter: <all paths except> VENDORS/* in the “widget logic” section showing under the widget.
Hope this helps. 🙂
