It sort of exists. If you're in OneDrive for business and you go to the shared with me section, you then have to click Classic OneDrive. You can still can't sync files, but if you go into a folder, the sync button is then there for me. If you're not seeing the sync button then, you may want to contact your IT Admin as there is a checkbox they have to make sure is on in the OneDrive Admin center that allows the sync button to be shown.
After syncing the folder (in this clunky way), it then creates a separate location on my computer where it syncs, rather than in the company onedrive account folder.
This are too many footnotes and gotchas to this process. Microsoft just needs to make this seamless like all of their competitors did 10+ years ago.
