HiFiBerry+Touchscreen How to rotate image

Hi
I am unable find a setting anywhere that allows me to rotate the image on the official rasberry touchscreen by 180°, which I need to do, otherwise I will need to rebuild the house.

Running 20230404 OS on a Rasberry Pi 4 Model B rev 1.2
DAC HD card
Official rasberry power supply, connected to wired 1GB WAN

Please advise, and thanks in advance fro your help.
Mike
