I recently asked DJI if/when the Enterprise would get IFM and, FWIW, their response was:
Hi, thanks for the inquiry. We're sorry that the intelligent flight mode can only be used in the DJI GO 4 app. However, we've received the same request from other DJI Forum members regarding the compatibility of the DJI Go 4 app to the Mavic Enterprise dual to possibly access the intelligent flight modes. For further updates, please pay attention to our official website. Thank you for your understanding.
