Works like a charm:

$ grep -R JUPYTERLAB_SETTINGS_DIR $EASYBUILD_INSTALLPATH/modules/all/JupyterLab/4.2.0-GCCcore-13.2.0.lua
/modules/all/JupyterLab/4.2.0-GCCcore-13.2.0.lua:setenv("JUPYTERLAB_SETTINGS_DIR", pathJoin(os.getenv("HOME"), ".jupyter", "lab", "user-settings"))

$ module load JupyterLab/4.2.5-GCCcore-13.3.0
$ echo $JUPYTERLAB_SETTINGS_DIR
/users/example/.jupyter/lab/user-settings
