Accessing via API data of type FILE in QuickSight

Hello,

I would like to update a Row Level Security rule by adding a new username using the Quicksight API. All RLS rules were initially created using the console and by uploading a file. Is it possible to update that file using the API? The datasource is set as FILE and i'm wondering if I can access and update that file via API. IF i can't, can I linked a RLS rule to a S3 file which i can update using the S3 api. thank you! G.
