Install JetPack 4.6.1 on reComputer Jetson-10-1-H0

We have recently purchased the Jetson Nano custom board mentioned in the subject of this post. It comes with JetPack 4.6 pre-installed.

My question is: how can I upgrade the JetPack from 4.6 to 4.6.1? My intention is to use DeepStream. The only version of DeepStream that works with JetPack 4.6+ is DeepStream 6, but this in turn requires JetPack 4.6.1.

It is possible to download the SDK Manager on an Ubuntu host and install it, but this process is equivalent to flashing the system again.
