Avoid screen tearing with KDE and Nvidia proprietary drivers

Create the file /etc/modprobe.d/nvidia-modeset.conf.
Add setting options nvidia_drm modeset=1 inside the file.
Then sudo update-initramfs -u in the terminal.
Restart.

This generates some input lag, but seems comparable to the default Intel setting with the integrated graphics.
Games play fine (e.g. FPS games).
