Hello @Devdatta Jadhav,
welcome to this moderated Azure community forum.
According to this page, the Nvidia Jetson Nano runs on Ubuntu as operating system. It has a 64 bits ARM processor.
If you look at this page, this operating system and processor combination is available as Tier 1 supported operating system. This means this combination is tested by Microsoft.
In the past, I got it working via a Hands-on Lab as seen in this blog post.
I'm not sure if this tutorial is still valid.
