I have queried the system with huawei P30 pro, with eglQueryString, it looks like support the EGL_ANDROID_get_native_client_buffer.

Yes, while we don't support this extension directly, it is indeed implemented in Android's EGL layer so you can rely on it. Have you been able to make the EGL route work?
