Can an OpenShift private cluster install use a custom DNS server

Solution Verified - Updated -

Issue

Using the IPI installer to create a private cluster is failing. This is being provisioned within an existing environment that has a custom DNS server configured in the local network.

Environment

OpenShift 4.x IPI installer (internal clusters installs only)
Cloud environment where DNS records are provisioned by the IPI installer (AWS, GCP, Azure)
