Disabling the "Use kernel from other session" option

Hello,

I have searched the documentation thoroughly but to no avail. At this point I would like to know if it is already possible to disable this “Use kernel from other session” feature and i’ve missed it? Does anyone know about this by chance?
For a bit of context, I would like several users to work on a jupyterlab session but not be able to use each other’s kernels.

Thanks
