It seems that your Lenovo Yoga 7 laptop may not be fully compatible with the Dynamic Lighting features. The ability to control brightness and effects for Dynamic Lighting devices is dependent on the device being recognized as a compatible HID LampArray device by Windows. If the options are greyed out, it could indicate that the laptop's keyboard lighting does not support the Dynamic Lighting functionality or that it is not recognized as a compatible device.
You may want to check if there are any firmware updates available for your laptop or if there are specific settings in the Lenovo Vantage application that need to be adjusted. Additionally, ensure that your Windows version is up to date, as Dynamic Lighting features are supported in Windows 10 version 1809 and later, as well as Windows 11.
If the keyboard light is on but you cannot change the color, it is likely that the keyboard does not support the Dynamic Lighting API, which is necessary for such control.
