Is there any way to adjust the game internal resolution on PC?

My monitor is 4K, and the game, while really awesome, is really demanding on my GPU. Most games allow upscaling via FSR or DLSS, but this game doesn't have any option. In fact, there is no way to even change the render resolution to something lower than 4K. 

My question is, does anyone know any trick to change the internal resolution (not the output resolution from the resolution menu)? Maybe somewhere in a config file? 

Otherwise, if EA is reading, maybe add a way to upscale with FSR or DLSS? The consoles already have something like this because the performance mode would not be possible otherwise, so I think it would be fair to add it to PC as well!

Thank you
