Dual display configuration with one monitor

I want to setup the following configuration:

I am using LEAP 42.2 with KDE desktop.
There is one touchscreen monitor connected to the VGA port (it’s a server PC).
Now I want to have a second (virtual) display that can be used to connect via VNC. Both displays (touchscreen, VNC) should show different things.

Either the display that is shown on the touchscreen as well as the second display should be auto logged in.

Any hints how to configure that are very welcome! Searching for such a case usually returns a configuration with multiple physical monitors.
