Parthian not sure what you mean by that, pip3.13 is installed on all of our servers.
If you're doing this locally on your own computer then use whatever version of pip you have installed. The pip version doesn't really matter, all pip does is download and install uv (which itself is a compiled Rust application).
If you'd rather not use pip you can also install with:
curl -LsSf https://astral.sh/uv/install.sh | sh
