Hi!

Yes, what I meant was that there is no built-in/supported option/command to do that. There are good reasons why this is the case, but there are workarounds that may or may not work like the one you mentioned. More examples are listed here:

Thus when I try to install newer MNE 0.21.0 using <<pip install mne>>, the older dependencies are not getting replaced by the latest versions of dependencies.  And I'm a bit skeptical, that the latest MNE might use the latest versions of the dependencies.
