ServiceNow and PagerDuty Integration - Turn off ServiceNow Incident Resolving when PagerDuty Incident Resolves

The Current Setup is When PagerDuty is resolved, it resolves ServiceNow Incident as well. What settings do we need to change that not to happen?

Requirement is when PD Resolves, it should not resolve ServiceNow Incident. All other bi-directional sync should be same as default.

Looking at: In PagerDuty Settings in ServiceNow -
Could see that Incident state value to use when PagerDuty resolves an incident field value is se to (6) Resolved which would resolve the Incident in ServiceNow.
If I have to change that field value there is no option to select Blank.
