If it is you have to use this command line. The file is not in either of the 2 packages in the last tarball I gave you to test. I just got through compiling the latest git and it is there.
I’ve done some tests with the 32bits rpiOS (5.10.63) with the same hardware.
RpiOS uses libcamera v0.0.0+3156-f4070274 (which is closed to the head of the repo: 3170 commits) and it works well on this 32 bits environment.

Not much I can do here as I do not have a camera to test with. I do know that since they came out with Bullseye OS they said the were going to redo their camera guide as things were different using libcamera/V4L.
Although things will have to be added manually in config.tx with an arch based OS one might install PiOS and look for changes in cmdline.txt/config.txt and make note of them.
