how to user build kernel file.. for android 10 OS.

when i checked android_build/kernel/ only prebuild is avaliable.. due to this i am not able to add drivers or access the gpios  in Android 10 OS.

i want to build complete kernel file as user build not using pre build.

and i want to link the drivers which i create in kernel .And allow access all the gpio and peripherial
