For some reason, this setting appears absent from the API. But you can create a basic version of this script like so:

     public Transform target;
     Quaternion initRotation;

     void Start() {
         initRotation = transform.rotation;
     }

     void Update()
     {
         Vector3 targetDir = target.position - transform.position;
         Quaternion lookRotation;
         if (locked)
             lookRotation = Quaternion.LookRotation(Vector3.up, targetDir)
             * Quaternion.FromToRotation(Vector3.up, Vector3.forward);;
         else
             lookRotation = Quaternion.LookRotation(targetDir, Vector3.up);
         
         transform.rotation = initRotation * lookRotation;
     }

Untested, but should work. Do tell me if you have any issues.

Edit: you can actually access them like this

     using UnityEngine.Animations;
     [...]
     GetComponent<AimContraint>().rotationAxis =  Axis.X | Axis.Z; // to tick every box except Y

or like this

     GetComponent<AimContraint>().rotationAxis = Axis.None; // to unlock the rotation

The "Freeze Rotation Axis" label is very confusing, considering that activating them is what allows the AimConstraint component to change them. "Constrained Axis" would make a lot more sense.
