If not, is there a possibility (software) that makes it possible?

Yes, this monitor can be split into two screens to work separately 👍

Yes, the monitor can be split into two separate screens with different inputs. E.g. one side Displayport and the other side HDMI input.

Hello
The monitor can be split into several windows. This does not depend on the monitor but on the operating system. As of Windows 11, you can drag the corresponding open application to the top of the screen. The various possible window divisions are displayed there.
Otherwise there is a tool from Micorosft: https://learn.microsoft.com/de-de...
I hope I have been able to help you

Unless you take a chainsaw... you can display two separate computers where the display is limited to 60Hz, then it's possible to manage screen sharing under Windows by separating the screen into two or more depending on the applications you want. I haven't found any software yet that would make this possible.
