m18 R2, lights configurations

1. Is is possible to configure M18 R2 such that the keyboard backlight comes up as inactive after boot-up, but it retains functionality associated with F7 key? (As I understand, you can totally disable keyboard backlight in BIOS, but that's not what I want to achieve.)

2. Is is possible to totally disable the blue light in the back of the computer (the one along the edge of the enclosure)?

I appreciate advice.
