Disable outbound connections to clm.sonatype.com

I have a Nexus Repository OSS instance running on DMZ where only access to nuget.org is available (for nuget proxy repository). The problem is that Nexus tries to access clm.sonatype.com and constantly throws exceptions in the logs. The UI will be stuck on “Loading…” until the attempted connection has been made. How can I disable outbound connections to this url?

The error appears when Nexus tries to do post and get to this endpoint:
http://my.nexus.com/service/rest/v1/user-telemetry/events/rte

I managed to disable rhc.sonatype.com following this guide:
