Answer: A word filter that lists the three brand names as blocked phrases
Word filters block custom words and phrases on an exact match, and AWS names competitor and product names as the use case. AWS guidance states that topic filtering should not be used to capture individual words or entity types such as a competitor name. The NAME entity type covers an individual's name and is not applied to names that are part of organizations, so it will not catch a brand. Content filters score fixed harm categories and cannot be pointed at chosen words.
