Microsoft makes it a pain, but you can still jump through some CLI hoops to use only a local user account to log in to Windows, rather than the cloud-conmected Microsoft account they try to funnel you into. Not logging into a Microsoft account prevents OneDrive from doing anything other than spamming you with notifications about how great it would be if you logged in and started using it. And you can still uninstall OneDrive after every major OS update that brings it back.
