You can use the softdevice API:

how to stop advertising and restart again?

going to sleep is nothing but the idle_state_handle.

Hi, when you disable the softdevice the LF clock is probably stopped and therefore the RTC2 will stop as well.

Not sure what you mean by "going to sleep". The softdevice is already power optimized so after advertising is stopped (or between the advertising events) the current consumption is as low as it can be while still having the LF clock and RTC running (~2uA). You should not disable the softdevice, just stop advertising.
