Trying to create Azure SQL single database- using DTU models

I have tried looking at both the older version of azureerm_sql_database and the new mssql_database documentation to find the one that best follows the model you do via the Azure portal. But no one seems to have a simple explanation for how to create only a single database that is DTU-based, and the alternatives I see are to use elastic pools, which feel unnecessary if you only have one database. Please help me with suggestions.
