Main thing is to know if your ISP cares or not. Mine does, so I use a vpn. You can set qbittorrent to only use the vpn so if it gets turned off then just nothing will download.

You can do that on windows just downloading something like qbittorrent and mullvad vpn. You can also set them up in docker containers if you are familiar with that. It allows you to have the vpn only affect qbittorrent rather than your whole PC.

I do all of this on linux as well but had originally set it up on windows.
