There is no such option.

OK. Thank you for the bad news ;)

Would we have that option if we use an
smtpd_proxy_filter,
i.e. spampd?

It is not a good idea to simply turn off Milters in the middle of
an SMTP session, because that would whitelist all mail that is sent
later in that same SMTP session. To fix that one would have to add
code to turn Milters back on in the middle of a session. That 
code is hard to maintain and because almost never executes and
therefore it will be buggy, suffer from bitrot and other badness.

Postfix does not know where the smtpd_proxy_filter will deliver
its output, so it cannot jump over the filter. Again, one can
keep piling junk on top of Postfix for rare corner cases, or
one can spend the cycles on something that benefits many people.

For good reasons, many filters have their own whitelisting features.
