A long time ago, we created an option called autorenew in the renewal configuration file in /etc/letsencrypt/renewal. It should be possible to set autorenew = False up at the top of an individual renewal configuration file and then have that particular certificate be skipped over entirely by certbot renew.
However, I think you may be the first user ever to ask about this on the forum, so I wouldn’t call this feature well-tested. I’d be glad to hear about how well it works!
