I believe it has been answered "you do not need to enable it, it is always enabled by z/OS" on all machines that support it (which is all machines on which z/OS runs).
As with many queries, it would help to understand what you are trying to accomplish, because perhaps use of key 9 is not something that will be of enough benefit to make it worth your while.. One caveat, if you do not attach your task using the KEY=NINE parameter of ATTACHX, then be aware of the rules governing the subpool in which your module is placed. If it lands in subpool 251 which is fetch-protected TCB key. So if your program is in subpool 251 key=8, you cannot successfully SPKA to key 9 within that program as then you will not be able to access your program's instructions. If your program lands in subpool 252 (key 0, not fetch-protected) that will not be a problem.
