Inside of your target venv workspace:
pipenv install ipykernel
pipenv run python -m ipykernel install --user --name=<name-of-pipenv-venv>
Make the name
value something that describes your current workspace. Can just be the directory/venv name.
Open a notebook and then select your new kernel.
Run the following (doesn't need your venv to be active):
jupyter kernelspec uninstall unwanted-kernel
