[SOLVED] How to install Proxmox Backup with ZFS for the root file system

[Fra]

We have:
* 2 x NVME 500G
* 2 x 6T SATA
on a 64G ECC RAM on a Hetzner ax41-nvme (no RAID hardware at all).

We would like to install PBS with ZFS for the root file system on the two NVME, but do not see the ZFS setup option while installing (ISO). How to do it?

Btw, we already installed (can re-install with no problem) without ZFS on the root file system: can we convert actual setup?

This is what we have now
