@dedemorton , this issue is indirectly related with the issues you have taken:

#4562
#4563

The change requested in this issue is included for the quickstart guides affected by the related issues when they say:

This functionality is available in all Elastic deployment models.

As soon as you update those two guides we will just need to update the remaining one (Unified Kubernetes Observability with Elastic Distributions of OpenTelemetry (EDOT)) on the scope of this issue and check that the prerequisites sections are kind of aligned.

I'll assign this issue to myself so I remember to do this.
