Sorry for the late post on this thread.
As you have already seen, disabling the IIS WebDAV module does not affect SharePoint WebDAV because SharePoint imlements its own WebDAV functionality. Rather than attempting to change permissions or deny access to _vti_*** paths through NTFS or IIS I would
URLScan to block the WebDAV verbs through [DenyVerbs] and block any paths through [DenyUrlSequences].
