Does the Jetson Nano SD card image come the kernels pre installed?

Hey, I am currently doing a project on the nano and was wondering if the kernel drivers are already pre installed. I was looking at the download page and noticed the L4T(BSP) package. Is that included in the SD card image or should I download it for the kernels? Thank you!

Hi UAVstreaming, the SD card image already includes the JetPack components pre-installed, including L4T BSP, CUDA Toolkit, cuDNN, TensorRT, VisionWorks, OpenCV, Multimedia API, and GStreamer. So you don’t need to download L4T separately from the SD card image.

Thanks for the reply, Dusty. The problem is I want to load some new kernels to get my USB modem working. How do I go about doing so?
