@NobbZ is right, Chocolatey is not meant to be a version manager.
I’ve even contacted the package author to see the possibility to provide more elixir versions based on otp compilation.
So… I started putting together my own version manager… I’m no expert and just started hacking around with Powershell for real after posting in here. For anyone interested:

PS.: The project is very very embrionary and lacks a lot of functionality to make it usable right now.
Currently, it can list branches and releases for Elixir and Erlang as well as download those versions.
I intend to keep working on it (It’s been two days hacking around so far)…
I mainly started this project because I was trying to start to learning Elixir/Phoenix and the vs code extensions that uses dialyxir was complaining about the version my elixir was compiled, so I ended up in this thread 
.
