SAML 2.0 Identity Provider - x509 Certificate Renewal

We are currently supporting an application that is integrated with an Enterprise Security Gateway for SSO via Keycloak.

Within our Realm we have created an Identity Provider that is configured using SAML 2.0 configuration settings. We established the integration four months ago and it has worked perfectly.

This weekend the Enterprise Security Gateway’s Public x509 certificate is being renewed. I cannot find a place to update this certificate within the Identity Manager’s configuration. Is there a way we can refresh / renew the public x509 certificate we are using without re-creating the Identity Provider?
