After furthering exploring this issue and relying on the configuration of the Address hub provided in the Address Data Management ArcGIS Solution, I was able to determine that the CSS style to overwrite the Row Class is in the site Footer HTML. I copied and pasted the <style>...</style> configuration from the Address hub Footer HTML section and pasted it into my own Hub site's Footer HTML and the Row CSS Class was successfully updated. Below is the <style>...</style> that I used.
