Hi Sachin,

Try the below script, and make sure of below points:

1. If you are having 4 checkboxes, then you need to write 4 onChange client script one for each checkbox. But code in each script will remain the same. Only replace the backend name of checkbox with your's [That's only change needed in the script]. For me this scripts works as per your requirement. In my example I have 5 checkboxes where you can select only 2 checkboxes (any).

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }

   var checkBoxes = ["checkbox1", "checkbox2","checkbox3","checkbox4","checkbox5"]; //Replace backend name of all checkboxes
var uncheckedBoxes = [];
var checkedBoxes = [];
checkBoxes.forEach(function(item){
if(g_form.getValue(item) == "false")
uncheckedBoxes.push(item);
else
checkedBoxes.push(item);
})
if(checkedBoxes.length == 2){
uncheckedBoxes.forEach(function(item){
	g_form.setReadOnly(item,true);
});
}
else{
	uncheckedBoxes.forEach(function(item){
	g_form.setReadOnly(item,false);
});
}
   
}

Let me know if this works for you.
