Ndless 3.9 not being reboot proof, Nover won't be able to adjust its settings (auto-overclock)
You can ask the author directly here:

(And it
doesn't look like nLaunchy (making ndless reboot-proof by reinstalling it, kinda) overclocks OSes 3.9 - You can open an issue on the repo, though, maybe Excale (the maintainer) can add that)
Edit: well, yeah, considering nLaunchy makes it reboot-proof, you could try that I suppose. But that supposes your hardware revision is compatible with it...
