how to stop SDP getting triggered when a value change in an array

Summary:

Hi Team,

We have created an array variables with around 10 data type objects as part of our requirement. We have created form and used oj-bind-for each to display the array in the form.
In the form, we have requirement to display the LOV for which we have created an SDP and used that SDP to display the LOV.

Now, the problem we are facing is if we update any value even in free text, the value chain is triggering the rest api of the SDP and it is triggering on every index.

For example, if I have array with 4 object elements and the object contain info like emp name, emp no, managers (LOV).
