without uninstalling/reinstalling DM?

Yes you should be able to delete the service books by going to options>advanced options>service books - menu key> delete.

Assuming you installed DM using the Redirector option... then the service books will likely be re-pushed to your device after they've been deleted from the handheld.

You should uninstall DM and reinstall using the BIS option... then delete the [Desktop] service books from the handheld.
