It depends, if you are using backup interfaces then EIGRP won't bring the line up obviously.
I suspect that you are using floating statics though, in which case, if you just specify passive interface then no adjacency will be formed regardless of the state of the interface. If you then specify a neighbor so it is unicast, it will bring the line up (an keep it up) if it is defined as interesting traffic. If it isn't seen as interesting, it will form an adjacency when the line is up (by some other interesting traffic) which will then break when the line goes down again.
