I have not seen an "official" Fico communication on Dedupe for Fico 10. Fico typically mentions important changes on new models when rolled out. Therfore, 45 days would be expected barring a communication ststing otherwise.
FWIW - the 3rd party article in the below link does state Fico 10/10T applies a 45 day Deduplication time period: https://www.firstcard.app/learn/vantagescore-4-vs-fico-10-differences
Here is a link to another article that summarizing some characteristics of Fico 10/10T and its BNPL variants.
