ERC is a feature within the SCT standard. For modern hard drives,
claiming "SCT" support is comparable to a bottled water supplier
advertising that their product is wet.

ERC on the other hand is a valuable feature that modern drive
manufacturers make you pay extra for.

I originally wrote that sentence as "Desktop drives do not." I added
"/green" to clarify that some non-enterprise, non-NAS drives aren't
marketed as desktop drives, but still lack ERC functionality.
Your ST1000DM003 is marketed as a desktop drive. Seagate's product page
for this model has links to other models for specialty use cases,
including NAS.
