Disable Terminal using helm chart for JupyterHub/Kubernetes

Hi All,
I am building JupyterHub infra in Kubernetes using helm (zero to Jupyterhub). everything went well, but I am stuck while trying to disable the terminal. We don’t want to provide users to have an explicit access to terminal.

I tried few configurations including adding extraConfig “c.ServerApp.terminals_enabled = False” and “c.Spawner.args = [”–ServerApp.terminals_enabled=False"]". but it didn’t work.

I also tried by adding additional script file as extraFiles for single user, but it is not being triggered.

Please suggest if someone has faced similar situation and have resolved the same. your help here is pretty much appreciated.

Thanks in advance,
