Nomad host_volumes in terraform?

When trying to run nomad on terraform, I was reading the docs for the nomad provider and came across the plugin_id field. Initially, my volume was mounted using the host_volume stanza under client via a config file. It looked something like this:

client {
  host_volume  "auth_db_vol" {
    path = "/home/auth/thingy"
    read_only = "false"
  }
} 

Any idea how would do this inside terraform entirely? I don’t know much about csi plugins, but if it helps, I am not using any cloud environment. I am running this on a single server and intend to store the data on it as well.
