Stability Matrix install & Python

Hi, I m a regular Forge user and i m planning on moving to Stability Matrix to install both Forge Neo and ComfyUI while using a shared folder for all that concerns checkpoints, LoRA, DoRA, upscalers, embeddings, etc. But before doing so i need some clarification regarding Stability Matrix install process and Python. Currently i have Python 3.11, 3.12 and 3.13 installed. My question is should i uninstall all of them to let Stability Matrix download Python by itself or will Stability Matrix be able to notice that i have those Python versions installed? Thanks in advance for your help.
