Are you using some operating system that doesn't have multi-user support by any chance? Otherwise, most modern operating systems allows you to have multiple users per machine, where their files are separated, so you could have one "normal" user you use for day-to-day, and one "streaming" user where you only do streaming from. That's how I make sure everything is separated for me when working VS streaming work (on Windows and Arch Linux, I'm 100% confident macOS has multi-user support as well)
