Yes, if you are running 1.8b, there is a SET_REQ entry point available to your list exit which would allow you to do this. Your exit would need to examine the SET options being passed one at a time, and, if it encounters a "CONCEAL", it could, say, change it to NOCONCEAL and return to LISTSERV with a return code of 2. The return code of 2 means a parameter has been modified. The exit could, of course, be nice and send mail back saying that CONCEAL is not valid for the list, etc. though that is a little more work on your part.
