I tried a lot of different methods,This can be done by notifying a dummy modify to keymap with such an operator.
I don’t think it’s a good way, but is there any other good way?

class SAMPLE_OT_DirtyKeymap(bpy.types.Operator) :
    bl_idname = "addon.sample_dirty_keymap"
    bl_label = "Save Keymap"

    def execute(self, context):
        km = context.window_manager.keyconfigs.user.keymaps["MyAddon"] :
        km.show_expanded_items = km.show_expanded_items
        for kmi in km.keymap_items :
            kmi.active = kmi.active
        context.preferences.is_dirty = True
        return {'FINISHED'}
