How to completely exclude a user from backups (still getting some system files)

I’m trying to fully exclude a user from backups in HestiaCP. So, in the Edit Backup Exclusions section, I’ve added * under all categories — Web Domains, Mail Domains, Databases, and User Directory, so that nothing should be included in the user’s backup.

However, even after doing this, the backup archive still contains some system-related files (like Hestia configuration, SSL, cron, and PAM data).

Is there a way to completely disable or prevent backup creation for this user, or to exclude these remaining system files as well?

I’d like the backup to be truly empty (or ideally not generated at all).
