I recently tried to fully rid myself of OneDrive and it took me over 48 hours to accomplish. The only working method I found involved fully enabling OneDrive, signing in, and waiting for a full sync. Only then was I able to tell it to stop syncing and finally remap Documents, Downloads, Pictures, etc.
The fact that I needed to log in, wait 24 hours for my account to unlock due to inactivity (!!!), and enable sync in order to disable it was enough for me to finally decide that Windows 10 will be my last Microsoft product. It may be a small annoyance, but to me it was the straw that broke the camel's back.
