Forcing conda to update package without downgrading others, ignoring any possible bad side effects

Trying to update conda gives

The following packages will be UPDATED:

  prompt_toolkit                                2.0.10-py_0 --> 3.0.0-py_0

The following packages will be DOWNGRADED:

  jupyter_console                              6.0.0-py37_0 --> 5.2.0-py37_1

Let's say I want to update prompt_toolkit without downgrading jupyter. I understand that if jupyter-console needs prompt_toolkit< 3.0 I could have a bad time, but what if I want to take that risk?

Is there a command like conda update prompt_toolkit=3.0.0-py_0 --only-look-at-this, where conda will just blindly install prompt_toolkit without even looking at things that depend on it?

From the conda update docs:

--no-deps

Do not install, update, remove, or change dependencies. This WILL lead to broken environments and inconsistent behavior. Use at your own risk.

Alternatively, if you want to install new dependencies, but not change ones that are already installed:

--freeze-installed, --no-update-deps

Do not update or change already-installed dependencies.
