yeah most games don’t have any DRM related to DLC on Steam
DRM on steam most of the time is limited to the base game and sometimes you can just run the binary without Steam
Even on games with denuvo you can use tools to pirate DLC (I did this for SMTVV)



You can try and it may work because a lot of games on Steam and Epic barely use the DRM.
I have portable installations of several games from Epic that I moved between Windows installs that just work by executing the game’s binary
The issue with Steam is that some games do use the Steam DRM to verify additional content, but even there are ways to bypass that in two ways.
