If you want to do that on Dovecot's side, look for sieve and vnd.dovecot.filter. See https://doc.dovecot.org/configuration_manual/sieve/plugins/extprograms/ and corresponding RFC for details.
Doing that directly in Dovecot might not be the most effective way but depends on your needs... Anyway, it would require a bit of scripting, basically you need to parse the message for MIME structure, find the "attachment" part, remove it, reassemble and return. Depending on your stack, you may take a look at the more effective place to do the filtering (as John Stoffel mentioned) -- e. g. many antivirus/antispam filters have the ability to filter out attachments... But if that's primarily for a single user or there's no way to plug it in prior Dovecot, it could fit perfectly.
