Power Bi uses data connectors to bring data into their tool for visualization. It can consume JSON/XML/CSV formats etc.
If your question is weather we have such a connector already - the answer is no. Can a client develop something for their use - yes, as long as the data is for personal use only. They will have to use Eikon .NET SDK for that.
As my colleague mentioned, Eikon data cannot be used outside the desktop on which it is consumed.
If they want to feed data into a non-desktop based implementation then they should consider consuming the data from another source such as Refinitiv Data platform (assuming that particular content set is available on RDP) which has the appropriate data licencing in place.
@Raya We also have an article discussing linking to PowerBI https://developers.refinitiv.com/article/how-integrate-dsstrth-data-power-bi-desktop The API is a different one but the process to link with BI will be similar.
