I've been working with InDesign for eBooks since InDesign CS5, and I've never heard of such a thing.
InDesign is not a template-driven program. It assumes that you will customize your layouts and settings, and usually create your own.
If you're talking about EPUB output, InDesign is designed primarily for people who have already created an InDesign document and want to create a EPUB file from a version of that document.
Tell us more about your workflow, and perhaps we can help you more.
