XBee 802.15.4 sleep remotely

I need to know if is possible to sleep remotely the XBee end node using SM=1 or SM=2 only configuring it in the XCTU this command remotely. Or it requires to manipulate XBee pins before?, I’m not sure how it works. How can I assert pin 9?

If you use any of the Pin sleep functions you must wake the module by driving the sleep request pin directly (locally) high or low as the case may be.
