Is there any way to force this game running more widely?

I'm using a 3440x1440 widescreen with this mod and SRWE(Simple Runtime Window Editor) tool to make this game borderless and wider.

Some scenes worked fine and amazingly immersive.

Some of them did not, just stuck in 16:9 or 4:3. (anyways, some of them, if you press START, you can see the the game has wide enough background to render in 21:9 or even wider)

So, it there an way to force this game to render more widely? I don't mind if the 3D models standing outside the black background at some scenes though may look wired.

Thanks for your great work.
