Make a custom handler (see
that checks mlist.umbrella_list, and if true add an X-No-Archive:
header to the message. E.g.

def process(mlist, msg, msgdata):
    if mlist.umbrella_list:
        msg['X-No-Archive'] = 'Yes'

The handler has to be in the pipeline prior to 'ToArchive'.

The header

X-Archive: No

also works.
