SELinux on Khadas VIM3 Android Pie

Dear all,
As I read in uboot (uboot/board/khadas/configs/kvim3.h), SELinux is disabled by default. I changed EnableSelinux=permissive to EnableSelinux=enforcing to enable SELinux, after that the OS can not start up, it loops at audit progress.
Has anyone enabled SELinux successfully? Does the VIM3 board fully support SELinux rules? If not, which process need to add rule?
P/S: I have used the latest commit ( Pie: V200617)

Thanks and Best Regards,
Ivan Do
