If your question is whether you can stop paying child support if you voluntarily stop having any contact with your child, the answer generally is "no".
Whether you see the child, the child will still need to eat, wear clothes, and have other necessities. The state does not want to be responsible for paying for the child.
If the other spouse has a new spouse who is willing to adopt the child and completes the adoption process and if you agree, the court may terminate your parental rights and therefore terminate your parental obligations.
You likely should review your facts and options with an attorney.
