Hi anonymous users-6549,
What did you mean organization one drive? Do you mean that a library in SharePoint sites?
If so, you could get the drive by the site path: GET /sites/{hostname}:/{server-relative-path}:/drive
For example, your site url is https://tenant.sharepoint.com/sites/test, you could get the url with the endpoint:
https://graph.microsoft.com/v1.0/sites/tenant.sharepoint.com:/sites/test:/drive
