Vector Tile Option Not Appearing in Layer Type

[HaskettGeorge]

Hello.

I am trying to publish a vector tile service to our portal, however when I attempt to do so I only see the options for Feature and Map Image in the Layer Type section.

The instructions I am trying to follow are the   Define a map in ArcGIS Pro and publish as a vector tile layer

instructions found at: Publish hosted vector tile layers—Portal for ArcGIS | ArcGIS Enterprise 

Am I missing a step?  Any assistance would be great.  Thanks!

I am using data stored on an SQL server that has been resgistered with the ArcGIS Server, and am using ArcGIS Pro 2.4.1 and ArcGIS Enterprise 10.7.1
