Recover controlfile with database in NOMOUNT state

Question

Hi,
I'm doing some tests, destroying my test envinroment. At this time i was trying to recover a "missing" controlfile both via RMAN and ALTER DATABASE command, but they all have failed because i cannot mount my database and as my researches show, i am only able to recover a controlfile if my instance is in MOUNT, but i cannot mount it because of the missing controlfile. I saw that via RMAN, i can recover the controlfile from a backup if i use static service registration. This is the only manner?
Thanks for your attention
