Setting my PyQt5 app to Portrait Orientation

Question

So I'm displaying my app on an external raspberry pi display but it is running the app on landscape. I want to display it in a portrait orientation with every subwidget inside to be in a portrait orientation automatically hopefully with only manipulating the QMainWindow.

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Saaf")
        self.setGeometry(0, 0, 480, 800)  # Adjust the resolution based on your screen size
        self.setWindowFlag(Qt.FramelessWindowHint)  # Remove window frame
        self.setWindowFlag(Qt.WindowStaysOnTopHint)  # Keep the window on top
        self.setFixedWidth(480)  # Set the fixed width to enforce portrait orientation
        self.setFixedHeight(800)  # Set the fixed height to enforce portrait orientation
        self.setStyleSheet(
            """
            QMainWindow {
                background-color: #51b09f;
                background-image: url('Images/icons10-recycle-500.png');
                background-repeat: no-repeat;
                background-position: center;
            }
        """
        )

        #set Title Screen
        self.screen1=TitleScreen()
        self.setCentralWidget(self.screen1)

if __name__ == '__main__':
    app = QApplication([])
    window = MainWindow()
    window.showFullScreen()

    sys.exit(app.exec_())
