I did it using Animator Override Controller

private AnimatorOverrideController overrideController;

    private void Awake()
    {
        overrideController = new AnimatorOverrideController(animator.runtimeAnimatorController);
        animator.runtimeAnimatorController = overrideController;
    }

    public void PlayerBaseAttack()
    {
        if (currentAttackType != null)
        {
            var pair = attackAnimationList.Find(p => p.attackType == currentAttackType);
    
            if (pair != null && pair.animations.Length > 0)
            {
                AnimationClip chosenClip = pair.animations[Random.Range(0, pair.animations.Length)];
    
                overrideController["Attack"] = chosenClip;
                animator.SetTrigger("Attack");
            }
        }
    }
