You can use the Microsoft Search API in Microsoft Graph to trim duplicate search results. Specify the trimDuplicates property in a searchRequest object to trim away the duplicate search results. The trimDuplicates property is only supported on files hosted in SharePoint. The default value is false.

      },
      "trimDuplicates": true
