Any doctrine that says you can go around Jesus for salvation is not a theology of the cross. Salvation is only found by going through Jesus. We cannot avoid the Human-God's life; His bloody, violent death; nor His glorious resurrection, and find salvation. We must go through Him.
So Jesus said to them again, “Truly, truly, I say to you, I am the door of the sheep. John 10, NASB
Jesus said to him, “I am the way, and the truth, and the life; no one comes to the Father but through Me. John 14, NASB
Anything different from what is revealed to us from Holy Scripture is false. False teaching damages people by teaching doubt of God's Word, then doubt upon those who teach truth. It places a person in a precarious place of unfaith. There are trust issues that cloud the vision of people that have been under false teaching.
To reject the death and resurrection of Jesus is a false teaching sown by Satan. Not all religions have Jesus, but they all contain a tinge of truth. The truth they share is usually from God's law. Do not lie, do not murder, do not steal, and more, are clear to non-Christians. What is evident to unbelievers belongs to the second table of the law, or how we treat one another. The difference between the Christian religion and non Christian religion lies in the First Table of the Law.
What is in the first table of the law is God's revelation about His character. Those are the things we do not see that we violate except as shown to us by The Holy Spirit. This would include knowing the person and work of Christ Jesus.
No, we cannot go around Jesus, the God-Man, and His perfect life; His bloody, violent death; and His glorious resurrection for our sake. To deny those things is saying you do not think you need forgiveness, because forgiveness can only be found in Jesus Christ, our only savior.
