A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
If you want to make something look like it was taken at night, take it at night, or indoors separated from the sunlight.
If you have an existing photo and can post it, that would give us strangers on the Internet some idea of how much work it might be to modify it. But no, it probably is not as simple as light/balance/curve editing.
I think I'm having difficulty understanding your question because it seems so off the wall.
Actually is hard to explain, that’s why I was no able to find a tutorial 😂
But I’ll try to give a simple example: imagine a room and 1 the first scenario it’s all closed only with artificial light (like a light bulb or a lampshade), and the 2nd scenario is the same room but now with a window in it and the daylight (natural light) now lighting the room.
Both photos of a subject and the whole room will look different and can be noticed, and I wanted to transform the photo taken in that day/natural light photo and make it look it was taken in the artificial one, without having to actually go and the the photo with the natural light (so its post editing).

There is a cinematic technique for this. I have not come across anyone doing this with photography, but the same principles should apply. Try looking for a tutorial on how its done for video.
Make it blue, make it dark.
Google day for night color grade tutorial. It’s used all the time in filmmaking. If you want it done right, study then shoot. If you are working on a preexisting shot, maybe some of those tutorials will help.
Very often interior night scenes are shot with bright light and looking fully lit but shaping the light matters. Then darkening in the edit further reduces the noise floor in your image.
Of course, you see it in most films and TV shows, this approach is called shooting Day For Night and comes down to a combination of your lighting setup and post processing.
