neoromanempire You can absolutely stop OneDrive from backing up Documents. Please see the first post of this master thread for more details:

An alternative is to create a new admin Windows account, making it local (as in, don't link your Microsoft account or any email address). A local account has no OneDrive tie-in by definition.
I dont see any way to do it on that post. My documents folder isnt listed as a folder i can opt out of syncing to onedrive.
