I read Assembly Guide for SparkFun JetBot AI Kit and know how to update the notebooks. I want to upgrade JetPack SDK to the latest 4.2.2 which supports DeepStream 4.0.1. The one comes with your SD image is 4.2.1. If I understand correctly, flashing image is the only way to upgrade JetPack for now. In this case, do you have a image built with 4.2.2?
