The concept of immortality as you make sense of it doesn't exist. Nothing is immortal there is a cycle of life that you can not simply ignore.
However for many religion anima (soul spirit in latin) is immortal but still it goes through changes and has a cycle that eventualy will lead to death (which is not an actual death but the soul will not be borned again at some point) this is a theory called anima mundi that was used by some pagans and has similarities with nirvan from buddism.
But to give you a clear answer.
No, you can not be immortal it's not possibe don't waste time and energy on that.
