You're wondering if there is a setting to enable automatic refresh for pages in Jive so that new content can be seen without automatically refreshing the page.
Currently, this is not possible in Jive. You will need to submit an enhancement request for it.
You can submit a support ticket with the details of your request so that the support team can submit an enhancement request to the product/development team.
Follow the steps in Creating a Product Enhancement Request.
Previously created request in the deprecated Jira - JIVESPECS-1426.
