No. Or rather, not yet. Valve has not released SteamOS 3 for anything other than the Steam Deck, but is planning to do so at some point in the future.

I honestly wouldn’t recommend SteamOS for anything other than a dedicated gaming device though. It excels at its use case of launching games via Steam, but for everything else it is quite cumbersome… I would much rather install a general purpose Linux distribution and run Steam on it.
