Hi @ShubhadaMaske 

I will not recommend creating a new field on Incident table, if this field used widely, better to create on task table.  here is example

To show and hide you can create ACL.

Hi @ShubhadaMaske ,

1. Create a checkbox field on the incident table/task table according to @Dr Atul G- LNG  comment. 
2. Create  a business rule for the checkbox to set it to mandatory:

   (function executeRule(current, previous /*null when async*/) {
       if (current.u_custom_checkbox) {
           current.setReadOnly('u_custom_checkbox', true);
       }
   })(current, previous);

3. Create a UI Policy to Control Checkbox Visibility

   function onLoad() {
       if (gs.hasRole('service_desk')) {
           g_form.setDisplay('u_custom_checkbox', true);
       } else {
           g_form.setDisplay('u_custom_checkbox', false);
       }
   }
