Someone have info, project or something to help about EPD display's. I hate the use of ARDUINO IDE, I'm an old man that want to understand the code, I don't like the ARDUINO "magic", because it use a lot of space and is very difficult to optimize

Thanks. It does not have the size that I need 3.7

Anyway, I'm going to start with this.

Going to need be more specific about the make, model, part of the screen and the controller ICs involved.

If you can get those, you can perhaps unpack what the Arduino libraries are doing, and what portions are need to initialize the display, and transfer frames.
