EV_ICM-20648

We have brought an EV_ICM-20648 and chipset for our wearable products and from that, we want to read data using NRf52 (nordic devkit).
But we don't have the driver file code. I have referred your Software downloads page but in that driver, files linked with STM and another controller.
So, can you please give me a separate driver file (.c and .h)? So, I can easily port in the Nrf board.
