I'm afraid that there is not much we can do here, unless someone figures out how kbd backlight control works on these newer devices. One thing which you could try is to reach out to Dell themselves and ask if they can help. Typically Dell is supportive of running Linux on professional laptops like this model. You could e.g. try emailing Dell.Client.Kernel@dell.com -- You may reply to this email to add a comment.
