Steam has no built-in tool to filter them. You can try running them without steam, but the easiest way is likely to check the PCGamingWiki page for a given game. The “availability” section should list what kind of DRM the game has, if any.

Not currently in a place where I can check, but I believe pcgamingwiki.com has this info.
