Any way to get UniFi device date code remotely?

Does anyone know of a way to retrieve the date code from a UniFi device remotely? I know it is on a sticker on the device, but we have many devices deployed and unfortunately have not been documenting the date codes before deployment. Now we need to know how old each device is so we replace them proactively as they age, and we really would like to avoid going to every client site to take pictures of the stickers on the devices.

I am not aware of any way to do it because I don’t think they save that into the firmware of the devices.
