How can I replace the custom toolbar above the File Display toolbar?

For my lister, how can I replace my custom toolbar, located above my File Display, with a different toolbar (This same toolbar opens with every File Display)? I want to do this because the same toolbar appears elsewhere in my custom lister.

It must have been added to Preferences / File Displays / Border. You can remove it from the same place.
