Is there anyone here successfully running rpi_camera with the latest HassOS 6.4 and core2021.8 above?

According to the documentation Raspberry Pi Camera - Home Assistant, the rpi_camera platform doesnt support Home Assistant OS installation type. This feature is still there, but not enabled within hassOS booting progress, so someone made the guide here to add some file to the boot partition so the rpi_camera can be enabled
The rpi cam worked fine with me untill hassOS 6.4 and core 2021.7.4, but when core 2021.8.0 released, it has gone.
So anyone here is still able to use this rpi_camera platform with the latest HomeAssistant OS 6.4 and core 2021.10.3, please let me know and show me how to bring this feature back :(((

OS 6.5 released, but still no luck then
