Anyone tried Anbox-4-arm64 yet?

Hmm, I've never recompiled my kernel before, so I don't really know what you mean by passing the flags through PKGBUILD, I'll investigate as to how-to recompile the kernel with the modules but the git report is not every clear (as in providing a step by step guide) about this...

Also it's a bit boring that I have to recompile the kernel, that means every time I update the kernel I'll have to recompile it with the modules?

What OS are you using? It might be helpful to ask on their forums for direction regarding this. The git issue is pretty all over the place, but if you're on Arch/Manjaro, you should be able to follow the updated install instruction in the Arch wiki: https://wiki.archlinux.org/index.php/Anbox
