Does it make sense to add additional fileSystems attribute for drives I don't want disko to manage/format like:

disko.devices.disk.main = { ... };
fileSystems = { ... };

Will this work correctly?

  grub = {
     efiSupport = true;
     #efiInstallAsRemovable = true; # in case canTouchEfiVariables doesn't work for your system
     device = "nodev";
  };

from here: https://nixos.wiki/wiki/Bootloader

But with disko, i'm getting some error :

       error: The option `virtualisation.vmVariantWithDisko.virtualisation.fileSystems."/etc/secrets".fsType' has conflicting definition values:
       - In `/nix/store/hzaj4d6ari2wq2cbg1j60n9zw42gnshy-source/nixos/modules/virtualisation/qemu-vm.nix': "9p"
       - In `/nix/store/7wf9q0mb1i43x9dr1qlyfaraq15n6sii-source/lib/interactive-vm.nix': "ext4"
       Use `lib.mkForce value` or `lib.mkDefault value` to change the priority on any of these definitions.

I believe this is because the disko vm image actually respects my partitions formats, but that's a bit of a problem for my specific usecase. I can remove the /etc/secrets partition definition in disko, and it works, but do I have any other option ?

I am a little lost trying to get disko working in this setup https://github.com/tcurdt/nixos-hetzner/blob/main/install-nixos.sh

I don't see that attribute set in the example config

What am I missing?
