I understand your point. The current OneDrive scanner is not a full replacement for the old Office Lens/Microsoft 365 scanner, especially for business use cases that require combining multiple photos, better document processing, and a faster field workflow.
At this time, Microsoft has retired Lens and removed some scanning capabilities from the Microsoft 365 app. There is no setting to restore the old scanner feature.
You can submit this feedback directly from the Microsoft 365 or OneDrive app (Help & Feedback) so the product team can see that users need the previous scanning features restored.

For now, using a third-party scanner app such as Genius Scan is a practical workaround if you need the features that were available in Office Lens.
