There is an option to get rid of the native kernel, set the following option to False:
KernelSpecManager.ensure_native_kernel : Bool Default: True If there is no Python kernelspec registered and the IPython kernel is available, ensure it is added to the spec list. I think that could help if I understood the requirement correctly.
