You can delete an ODS scheduler when it's no longer needed.
Note: To delete an On-Demand sandbox operations scheduler, you must have the Sandbox_API_User role with a
tenant filter in the format “<realm-id>_sbx” in Account Manager. For example, to
delete an ODS scheduler in the realm “abcd”, you must have the Sandbox_API_User
role with tenant filter “abcd_sbx” in Account Manager.
