Hi there,
Thank you for contacting us!
There is no such option in the API to disable the breadcrumbs (except for disabling the whole drilldown functionality with
allowTraversingTree option).

But, I can suggest you a CSS workaround. Simply set the display: none on both button and separator classes, and it won't show up again.
Take a look at the CSS tab:

Let me know if that's what you wanted to achieve!
Best regards
