Windows 10: Lock screen can be swiped away
Is there a configuration to avoid this behavior or inactivate touchscreen gestures when screens are locked?

Yes, there's a configuration: "Disable the Swipe Feature of Windows 10"
For Windows 10 users with a touch-enabled device, it is possible to enter Task View by swiping left from the edge of the screen. To stop this from happening, you can disable this swipe feature by Windows group policy:
Computer Configuration > Administrative Templates > Windows Components > Edge UI ("Rand-UI" in German versions)
