Hi There - yes we have a version of the connector that can handle query folding, but it is not the version MS is shipping currently (we are waiting for them to update to this version now). If you want the version that supports native sql and query folding, please download the latest from our MongoDB Download Center: Download Power BI Connector | MongoDB
Don’t forget to download both the connector and driver (odbc) as both have code to support the native sql and query folding.
Best,
Alexi
