Software options for DJI Mavic 3M multispectral data

I am currently using an DJI Agras T40 in high value crops. I will be getting a demo unit for the Mavic 3M to play around with. I am hoping to use the 3M for prescription maps as well as getting counts of our plants.

What software is out there for free, or to demo for the data the 3M will give me? The NDVI functionally is very interesting but I don't know where to start to process the data to integrate with the T40.

I would appreciate being nudged in the right direction. Thanks!
