Rootless docker with rclone image?

Do you think, guys, it is possible to run rclone image on rootless docker? I started enforcing my homelab so i would like to set as much obstacles as it is possible to discourage hacker from continuing his job (at least on my network).

Although i started with containerizing everything, i'm still asking myself if it is not better to have everything within it's own enviroment, meaning VMs via Proxmox. Do you guys have experience with this as better way of protection?
