Can we configure the path of 'config.toml' for containerd?

According to https://docs.k3s.io/advanced?_highlight=config.toml#configuring-containerd, we don't have a way to set the path of 'config.toml' in k3s, via arg or environment variable, etc. However, I'm confused if we really don't.

To provide context, I'm trying to install nix-snapshotter, but I have some problems (you don't need to read the entire post)
I suppose that the Nix script of nix-snapshotter configures k3s to use some other config.toml file for its purpose, but AFAIK there is no way to do it. This prevent me from debugging the issue and I'd like to know the way if we have one. As you can see nix-snapshotter repo, it has a patch of k3s but It doesn't look related to configuring config.toml path.

No. You cannot change JUST the path of the containerd config.toml, nor the path of the user-provided template (config.toml.tmpl). You can set the data-dir, which will move /var/lib/rancher/k3s somewhere else (and the containerd config file along with it) but you cannot set the path of just that file.
