According to the ''Calibration clock output'' chapter in RM0038, on other than Cat1 devices you should be able to achieve that by setting the asynchronous prescaler to divide by 2 (PREDIV_A = 1) and the synchronous then to divide by 16384; and having COSEL bit set. But doing so has consequences e.g. on power consumption, RTC calibration - read thoroughly the whole RTC chapter.
