When something is "not final," it means that it is not yet completed or fully decided upon. There are several synonyms that can be used to replace this phrase, including "provisional," "tentative," "preliminary," "incomplete," and "unfinished." Each of these words has a slightly different connotation, but all convey the idea of something that is still in progress or subject to change. For instance, "provisional" implies that something is temporary or conditional, while "preliminary" suggests that it is an early stage of development or planning. Whatever word is chosen, it should be clear that the thing in question is not set in stone and may still be subject to revision.
