Installing python packages when using PyCharm Gateway remote development

Question

I work in an environment where remote development is a must and 'no code on local pc' is enforced.

I am looking for the options of python remote development using Pycharm to develop on remote server that has no internet connectivity. The local PC used for development is connected to internet.

In this case, can one use conda and pip on the remote server via pycharm console/terminal and install python packages while using the internet connection from the SSH and your local PC? This will be a cool feature if it exists.

I know you can install python packages by saving them locally and then transferring to the remote server and installing there, but then it becomes a pain to manage packages and not from the same development environment (pycharm)...
