cant remove shortcuts

Hi guys, Im tryign to remove the camera shortcut from my lockscreen. Now this phone is a Nubia and has some customisaiotn so lockscreen apps dont work on it and there is no options in the settings either. Anyways I have decomplued and foudn where the I believe the shortcut is being placed in a file called "keyguard_bottom_area.xml" I have tried two things
1) deleting the whole string
<com.android.systemui.statusbar.KeyguardAffordance View android:layout_gravity="end|bottom|center" android:id="@id/camera_button" android:layout_width="@dimen/keyguard_affordance_width" android:layout_height="@dimen/keyguard_affordance_height" android:src="@drawable/ic_camera_alt_24dp" android:scaleType="center" android:tint="#ffffffff" android:contentDescription="@string/accessibility_camera_button" />
that results in a crash on startup

2) adding visibilty gone
<FrameLayout android:id="@id/preview_container" android:layout_width="fill_parent" android:layout_height="fill_parent" />
<com.android.systemui.statusbar.KeyguardAffordance View android:layout_gravity="end|bottom|center" android:id="@id/camera_button" android:layout_width="@dimen/keyguard_affordance_width" android:layout_height="@dimen/keyguard_affordance_height" android:src="@drawable/ic_camera_alt_24dp" android:scaleType="center" android:tint="#ffffffff" android:contentDescription="@string/accessibility_camera_button" android:visibility="gone" />

this seems to have no effect at all, shortcuts are still there and clickable.

Here is the whole code, any idea how i can make this go away?
