I did not find the preferred-dir parameter in the help manual
Should I use it this way?

JupyterLab - An extensible computational environment for Jupyter.
This launches a Tornado based HTML Server that serves up an HTML5/Javascript
JupyterLab client.
JupyterLab has three different modes of running:
* Core mode (`--core-mode`): in this mode JupyterLab will run using the JavaScript
assets contained in the installed `jupyterlab` Python package. In core mode, no
extensions are enabled. This is the default in a stable JupyterLab release if you
have no extensions installed.
* Dev mode (`--dev-mode`): uses the unpublished local JavaScript packages in the
`dev_mode` folder. In this case JupyterLab will show a red stripe at the top of
the page. It can only be used if JupyterLab is installed as `pip install -e .`.
* App mode: JupyterLab allows multiple JupyterLab "applications" to be
created by the user with different combinations of extensions. The `--app-dir` can
be used to set a directory for different applications. The default application
path can be found using `jupyter lab path`.
Subcommands
===========
Subcommands are launched as `lab cmd [args]`. For information on using
subcommand 'cmd', do: `lab cmd -h`.

Options
=======
The options below are convenience aliases to configurable class-options,
as listed in the "Equivalent to" description-line of the aliases.
To see all configurable class-options for some <cmd>, use:
<cmd> --help-all
--debug
Set debug level for the extension and underlying server applications.
Equivalent to: [--ServerApp.log_level=DEBUG --ExtensionApp.log_level=DEBUG]
--show-config
Show the application's configuration (human-readable format)
Equivalent to: [--Application.show_config=True]
--show-config-json
Show the application's configuration (json format)
Equivalent to: [--Application.show_config_json=True]
--generate-config

Prevent the opening of the default url in the browser.
Equivalent to: [--ServerApp.open_browser=False --ExtensionApp.open_browser=False]
--autoreload
Autoreload the webapp
Enable reloading of the tornado webapp and all imported Python packages
when any changes are made to any Python src files in server or
extensions.
Equivalent to: [--ServerApp.autoreload=True]
--script
DEPRECATED, IGNORED
Equivalent to: [--FileContentsManager.save_script=True]
--no-script
DEPRECATED, IGNORED
Equivalent to: [--FileContentsManager.save_script=False]
--core-mode
Start the app in core mode.
Equivalent to: [--LabApp.core_mode=True]
--dev-mode
Start the app in dev mode for running from source.
Equivalent to: [--LabApp.dev_mode=True]

Equivalent to: [--LabApp.extensions_in_dev_mode=True]
--log-level=<Enum>
Set the log level by value or name.
Choices: any of [0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL']
Default: 30
Equivalent to: [--Application.log_level]
--config=<Unicode>
Full path of a config file.
Default: ''
Equivalent to: [--JupyterApp.config_file]
--ip=<Unicode>
The IP address the Jupyter server will listen on.
Default: 'localhost'
Equivalent to: [--ServerApp.ip]
--port=<Int>
The port the Jupyter server will listen on.
Default: 8888
Equivalent to: [--ServerApp.port]
--port-retries=<Int>
The number of additional ports to try if the specified port is not
available.
Default: 50

--notebook-dir=<Unicode>
The directory to use for notebooks and kernels.
Default: ''
Equivalent to: [--ServerApp.root_dir]
--browser=<Unicode>
Specify what command to use to invoke a web
browser when starting the server. If not specified, the
default browser will be determined by the `webbrowser`
standard library module, which allows setting of the
BROWSER environment variable to override it.
Default: ''
Equivalent to: [--ServerApp.browser]
--pylab=<Unicode>
DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
Default: 'disabled'
Equivalent to: [--ServerApp.pylab]
--watch=<Bool>

Default: False
Equivalent to: [--LabApp.watch]
--app-dir=<Unicode>
The app directory to launch JupyterLab from.
Default: None
Equivalent to: [--LabApp.app_dir]
Examples
--------
jupyter lab # start JupyterLab
jupyter lab --dev-mode # start JupyterLab in development mode, with no extensions
jupyter lab --core-mode # start JupyterLab in core mode, with no extensions
jupyter lab --app-dir=~/myjupyterlabapp # start JupyterLab with a particular set of extensions
jupyter lab --certfile=mycert.pem # use SSL/TLS certificate
To see all available configurables, use `--help-all`.
