Someone may provide a better answer than me (I just started), but since you can’t install their OS (EDIT: may be possible to install it, check comments below mine), it seems like you’ll have to use libcamera for now. I don’t have a 2nd SD card for my Zero 2 so I’m using Libcamera to take pics: Raspberry Pi Documentation - Camera.
Without the Openflexure’s color compensation the colors will be screwy, but you can compensate slightly by using different color tuning profiles. The imx219_noir.json one will reduce pinkness. Raspberry Pi Documentation - Camera.
