@ScottFortman1 - here is how to delete the Subtype field in ArcGIS Pro.
These steps should have worked for you in Pro as well.
ArcGIS Pro 3.2.2 > Data Design > Fields
"Delete" is disabled for the *Subtype field.
Workaround
ArcGIS Pro 3.2.2 > Data Design > Subtypes
Subtypes > Create/Manage
Subtype Field: <Clear all subtypes...>
Click OK
Click Save
Close the Subtypes tab
Open the Fields tab
select the Subtype field > right click > choose delete
Click Save
The Subtype field was removed.
