There is no publicly available evidence that the late actor Cameron Boyce (1999–2019) expressed any romantic or personal preference for individuals from Trinidad, or any other specific region.
Boyce's legacy is his acting (Jessie, Descendants, Grown Ups), philanthropy (Thirst Project, epilepsy awareness), and kindness remembered by colleagues. Speculating on his personal attractions reduces a meaningful life to gossip.
If you're interested in Caribbean culture, Trinidadian heritage, or Boyce's actual charitable work, those are rich topics worth exploring.
