Tx2nx developer kit?

Does tx2nx have the developer kit in a package like nano? Because my system is ubuntu20.04, I don’t want to reinstall.

The TX2 NX dev kit does exist, and it uses an SD card the same way the Nano dev kit does. If you are speaking of an NX module, and wondering if it works on a dev kit board, then I don’t know (but I suspect it works with a change to PINMUX). An NX and Nano SD card would not be cross-compatible. Not sure if I’m answering the details you are interested in.
