Using OV9281 with external trigger and libcamera

Raspberry Pi Cameras
1
  1. Model number of the product(s)?
    OV9281 UC-599
  2. What hardware/platform were you working on?
    Raspberry PI 4 - Bullseye 64 bit

Previously we used your - now deprecated - arducam mipi userland driver. We now considered to switch to libcamera since we want to switch to Bullseye 64bit, too.
My question is this: Can we use the external trigger of the OV9281 in combination with libcamera and acquire the image in OpenCV?
I couldn’t find any documentation on this, unfortunately.
