Hello JoskoCRO,
- Can I do that from the terminal e.g. without having physical access to device?
- Are there any streamlined instructions for this? Because I saw your online instructions mention 5.x only ?
Yes, you can refer the following link for OTA update instruction.
NVIDIA Jetson Linux Developer Guide : Over-the-Air Update | NVIDIA Docs
- Does 4.6.2 support installing Jetpack-runtime only (without Jetpack-dev) as 5.x does ?
The installation of JetPack runtime components only is supported from JetPack 5.0.2.
