Unfortunately, no.  This is a specific goal for Expat 3.0 however.

What you can do in the current version, in addition to setting a flag,
is to clear all the handlers *except* the external entity reference
handler.  This handler should be set to something that always
indicates an error occurred, and XML_SetParamEntityParsing() should be
called with XML_PARAM_ENTITY_PARSING_ALWAYS (unless you're already in
the document body, since it makes no sense then), so that Expat will
exit as quickly as possible.
