[Q] Can I remove default GUI on Android 4?

I want to create a generic x86 rom based on Android.

I just want to create an android-based linux distro without GUI, I want to run only a bash shell on the distro. It is for a personal project.

I need to install Android packages without graphical interface and I need to build rom from scratch.

Do you have any idea how can I remove the gui from an existing android rom?

If not, do you know how can I not add the gui on the build rom from scratch?

Even if it is not possible to remove the GUI.

Can I create a custom OS gui for my customize build rom?

Cheers,
