How can I use Excel from SQL Server 2019 with PolyBase?

Microsoft.SqlServer.DataWarehouse.DataMovement.Common.ExternalAccess.OdbcUtil.GetTableType()

ok. I look this  dll code.

public static void GetTableType(string connectionString, int connectionLoginTimeout, string catalogNameArgument, string schemaNameArgument, string tableNameArgument, out List<string> fieldNameList, out short[] dataTypeArray, out int[] columnSizeArray, out int[] bufferLengthArray, out short[] decimalDigitsArray, out short[] nullableArray, out int[] ordinalPositionArray, out List<string> typeNameList)
{
    //IL_0151: Expected O, but got Unknown
    if (connectionString == null)
    {
        throw new ArgumentNullException("connectionString");
    }
    NativeOdbcConnection nativeOdbcConnection = new NativeOdbcConnection(connectionString, CreateOptionFlags.ReadExternal, string.Empty);
    nativeOdbcConnection.ConnectionLoginTimeout = connectionLoginTimeout;
    nativeOdbcConnection.EnableConnectionPooling = true;
    using (NativeOdbcConnection nativeOdbcConnection2 = nativeOdbcConnection)
    {
        IntPtr fieldNames = IntPtr.Zero;
        IntPtr dataType = IntPtr.Zero;
        IntPtr columnSize = IntPtr.Zero;
        IntPtr bufferLength = IntPtr.Zero;
        IntPtr decimalDigits = IntPtr.Zero;
        IntPtr nullable = IntPtr.Zero;
        IntPtr ordinalPosition = IntPtr.Zero;
        IntPtr typeNames = IntPtr.Zero;
        int numFields = 0;
        try
        {
            nativeOdbcConnection2.Open();
            if (!DmsNative.OdbcGetTableType(nativeOdbcConnection2.OdbcConnHandle, catalogNameArgument, schemaNameArgument, tableNameArgument, out fieldNames, out dataType, out columnSize, out bufferLength, out decimalDigits, out nullable, out ordinalPosition, out typeNames, out numFields))
            {
                ThrowMppSqlException("OdbcUtil.GetTableType, error in OdbcGetTableType", nativeOdbcConnection2);
            }
            fieldNameList = MarshalIntPtrToStringList(fieldNames, numFields);
            dataTypeArray = new short[numFields];
            Marshal.Copy(dataType, dataTypeArray, 0, numFields);
            columnSizeArray = new int[numFields];
            Marshal.Copy(columnSize, columnSizeArray, 0, numFields);
            bufferLengthArray = new int[numFields];
            Marshal.Copy(bufferLength, bufferLengthArray, 0, numFields);
            decimalDigitsArray = new short[numFields];
            Marshal.Copy(decimalDigits, decimalDigitsArray, 0, numFields);
            nullableArray = new short[numFields];
            Marshal.Copy(nullable, nullableArray, 0, numFields);
            ordinalPositionArray = new int[numFields];
            Marshal.Copy(ordinalPosition, ordinalPositionArray, 0, numFields);
            typeNameList = MarshalIntPtrToStringList(typeNames, numFields);
            if (numFields == 0)
            {
                ErrorUtil.GenerateUserVisibleException(SR.TableDoesNotExist(tableNameArgument));
            }
        }
        catch (DmsSqlNativeException val)
        {
            DmsSqlNativeException ex = val;
            throw GenerateUserVisibleException(ex);
        }
        finally
        {
            FreeIntPtrArray(fieldNames, numFields);
            Marshal.FreeCoTaskMem(dataType);
            Marshal.FreeCoTaskMem(columnSize);
            Marshal.FreeCoTaskMem(bufferLength);
            Marshal.FreeCoTaskMem(decimalDigits);
            Marshal.FreeCoTaskMem(nullable);
            Marshal.FreeCoTaskMem(ordinalPosition);
            FreeIntPtrArray(typeNames, numFields);
            nativeOdbcConnection2.Close();
        }
    }
