Currently there is no way to limit this scan.
If you have access to the Google Play store you could try using the Calibre Companion
(wireless require) app to connect to calibre instead of MTP. This app does allow you to limit the directories scanned. For my device to connect to calibre via Calibre Companion it takes about 1 minute and 18 seconds. This time includes time to scan the existing 2026 books on my device and update any metadata that may have changed since my last connection to calibre.
