You can enable independent headphone by specify hint indep_hp=1 by early
patching for desktop using realtek or idt codecs

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/Documentation/sound/alsa/HD-Audio.txt

- indep_hp (bool): provide the independent headphone PCM stream and the
corresponding mixer control, if available

Usually only pincap of those green jacks and retaskable io jacks support HP

You cannot use black line out as headphone since it lack HP amp
