The activation of the virtualenv is unnecessary (one can execute pip/python directly from it), and the configuring of your local pyenv interpreter is also unnecessary, it can create a virtual environment with one directly:

  pyenv virtualenv python3.12 .venv
  .venv/bin/python -m pip install pandas
  .venv/bin/python

Not quite one command, but a bit more streamlined; I guess.
