Use this in conjunction with the Soql.SortOrder class's setNullOrder method.

Soql.SortOrder sortOrder = new Soql.SortOrder(
  Opportunity.CloseDate,
  Soql.SortDirection.DESCENDING
)?.setNullOrder(
  Soql.NullOrder.NULLS_FIRST
);
Soql query = DatabaseLayer.Soql.newQuery(Opportunity.SObject)
  ?.addOrderBy(sortOrder)
  ?.toSoql();
