Nvidia just release a major firmware update for the DGX Spark which substantially reduces idle power consumption when the ConnectX-7 adapters are not in use: https://forums.developer.nvidia.com/t/dgx-spark-software-updates-02-2026/360362
Any ETA on when this update will be available for the HP ZGX as well? And will it be available via fwupdmgr as with other DGX Spark vendors?
