No, if there’s nothing, it’s not using one of the big DRM systems.
There’s a good chance it doesn’t use any DRM, but the only way to know for sure is to install it and try to run it without Steam (rename Steam dir and Steam exe just in case). Some games use Steam DRM or otherwise rely on Steam, so this is to rule those out too.
Also if you prefer a more thorough listing, check out the “Detected Technologies” section of SteamDB. I just chose a random game as an example of something with just Steam drm. https://steamdb.info/app/2062430/info/
There is a DRM section on the sidebar of the steam store page that tells you.
Did you mean this? If there is nothing written, does it mean the game is DRM free as if we were on GOG?

Oh I’m gonna have a look at my games out of curiosity then.
