If salvation is by faith, and faith comes by hearing the word of Christ, can we be saved without having heard of Jesus?

The Bible says > It is by grace that you are saved, by the means of faith. And it does not come from you, it is the gift of God’. (Eph 2:8). > So faith comes from what we hear, and what we hear comes from the word of Christ.’ (Rom 10:17). According to the passages of the Bible quoted (Ephesians 2:8 and Romans 10:17), faith and grace are necessary for salvation. However, these passages also emphasize the importance of hearing the word of Christ. In this context, is it possible to be saved without having heard of Jesus? Can we be saved without having heard of Jesus?
