Proxomox-nixos config persistence using impermanence

[hatch01]

Hi,
I installed proxmox-nixos without troubles on my nixos.
However, I am using impermanence.
I added these directories to be persistent:

    environment.persistence."/persistent".directories = [
      "/var/lib/vz"
      "/var/lib/pve-cluster"
      "/var/lib/pve-firewall"
      "/var/lib/pve-manager"
      {
        directory = "/etc/pve";
        # user = "root";
        # group = "www-data";
      }
    ];

The problem is that /etc/pve is a directory controller by fuse where even the root user cannot delete everything's
I tried to add programs.fuse.userAllowOther = true; to my config as mentioned by the impermanence doc, but this seems not to be enough.
(it seems applied correctly /dev/fuse on /etc/pve type fuse (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other)

May it be possible to simply change the folder where proxmox saves its data?
Having this directory as a parameter would be pretty simple for impermanence user to move to their non formatted directory without fighting with fuse access.
