How to pass parameters to config.toml.tmpl files

[liyang516]

I refer to https://docs.rke2.io/advanced and https://github.com/k3s-io/k3s/blob/master/pkg/agent/templates/templates_linux.go docs，
I know /var/lib/rancher/rke2/agent/etc/containerd/config.toml.tmpl is the customization file， but I don't know how to pass parameters to config.toml.tmpl files.

For example：

[plugins."io.containerd.grpc.v1.cri"]
{{- if .DisableCgroup}}
  disable_cgroup = true
{{end}}

So where or how to set the value of "DisableCgroup" ?
