We are using Microsoft Purview and would like to remove any default Microsoft Classifications and Classification Rules that we don't require (please see picture below).

These are pre-configured and tested Sensitive Information Types from Microsoft that cannot be deleted from a tenant. These are very accurate and heavily trained information types that may or may not be leveraged by your organization, but cannot be deleted.
