Set whether qmlscene (Qt Quick 2 application) should use the system's standard colors, fonts, etc. (like QApplication::desktopSettingsAware)

I want my Qt Quick 2 program to use default Qt Fusion Style, but not system style. When I had Qt Quick 2 Application (see this thread [qt-project.org]) I used this line in main.cpp: QApplication::setDesktopSettingsAware(false); How can I specify that in qmlscene? Is that possible? I really like system integration by default but my teacher hates my dark programs (I have KDE with Obsidian Coast color scheme).
