How to encrypt content of docker volumes? - eviltoast

I would like to run Paperless in my homeserver. While this server is not running sensitive data, this would change once paperless gets to manage all my invoices, bank statements, health docs and so on. So while running my Proxmox VMs and LXCs unencrypted, in this case I’d like to encrypt paperless-ngx data so that if someone steals the machine, manual decryption would be necessary. Does anyone have an idea how to achieve that?
