[exim] smtp_return_error_details for specific routers only?

Hello,

one of the routers in my exim configuration leaks some sensible information
if it fails. Is there any way to suppress this for this single router only?

I know that it is possible to set "smtp_return_error_details = false" but
this changes the behavoir of all routers and I have a strong interest not
to suppress some very helpful information which are written by other
routers.

Any ideas?
