QIcon HmsUiHelper::createIconFromSvg(const QString& svgFilePath, const QColor& color, int width, int height)

    QPainter painter{ &pixmap };
    painter.setRenderHint(QPainter::Antialiasing);

    colorizeEffect->setColor(color);
    item.setGraphicsEffect(colorizeEffect);
    scene.addItem(&item);
    
    QPixmap resultPixmap{ width, height };
    resultPixmap.fill(Qt::transparent);
    
    QPainter resultPainter{ &resultPixmap };
    scene.render(&resultPainter);

}

The result demo-code using QGraphicsColorizeEffect. Thank you musicamante!
