Lenovo Legion Y720 questions...

I used abdulilah's guide and everything is decent there, except the audio which is done with AppleHDA, that does't work for me, it's extremely buggy and no idea how to replace it with AppleALC. Now trying to install his keyboard driver or whatever to have it working after sleep, maybe you have an idea what kext / aml is used for thet ?

Since you have an ELAN trackpad (I assume), you’re stuck with the outdated, closed-source ELAN kext. I had very bad experience with it on my old laptop so I had to make sure that my new Y520 had a Synaptics trackpad before buying it.

Then you should report your trackpad driver issues to @RehabMan.
