Enable IMX577 via CCI on Taloss EVK Core Kit. The Talos EVK board does not include a camera sensor by default, this overlay reflects the possibility of attaching an optional camera sensor. For this reason, the camera sensor configuration is placed in talos-evk-camera.dtso, rather than modifying the base talos-evk.dts.

You need to add talos-evk-camera.dtbo to dtb-y if you want it preserved and able to be installed (via dtbs_install). If you don't want that, then why is it a .dtbo? Looks like other .dtbo's might have the same issue.
