The Dun & Bradstreet Corporation is an American company that provides commercial data, analytics, and insights for businesses. Dun & Bradstreet is a registered data broker (California, Oregon, Vermont, Texas) that aggregates data on businesses and the people who represent them. The Trust Centre page does not host a self-service opt-out itself; it links out to a data subject rights request mechanism (the word 'here' in the Individual Rights section) and to a Global Compliance & Ethics contact, so you must follow that link or contact them directly. No processing timeline or ID-verification requirement is stated on this page, so the 45-day statutory default is assumed.
