Does anyone know how to connect to a SQL server forcing NTML with a .NET 6 SqlClient connection string

var cnn = new SqlConnectionStringBuilder()
{
ApplicationIntent = ApplicationIntent.ReadWrite, 
DataSource = "[Server]",
InitialCatalog = "ProjectX", TrustServerCertificate = true
, UserID = "Domain\\UserName", Password = "******************"
};

Reason: Attempting to use an NT account name with SQL Server Authentication.
