Shader on a game?

There are shaders for minecraft, which I also use and so on, now I was wondering whether there are also shaders that you can put on other or not so well-known games or where you can download something like that. If it is important: The game (star stable) has graphics like fortnite, but is not a shooter but is about horses. So you can compare the figures and the graphics really well with fortnite.

Would be really nice if someone had an answer.
