Hi,  
Sorry for the delay I was in holyday.  
I just tried to pass the environment variable but it did not fix the issue.

I tried to pass it using:

```auto
c.KubeSpawner.environment = {
    'JUPYTERHUB_SINGLEUSER_EXTENSION': '0'
}

```

```auto
c.Spawner.environment = {
    'JUPYTERHUB_SINGLEUSER_EXTENSION': '0'
}

```

(With quote and without)

And directly throught the charts with the extraEnv variable:

```auto
extraEnv: 
    JUPYTERHUB_SINGLEUSER_EXTENSION: '0'

```

I might have missed the right way to pass it to the application.
