Bulk import T-SQL ignoring double quote (") - sql

Question

I'm using an original script I found a long time ago to create a bulk import of many CSV files into an SQL database. With minor adjustments the script is working for me, but I can't get rid of the double quotes as FIELDQUOTE.
DECLARE #Path NVARCHAR(255) = 'D:\TEMP\'
DECLARE #RowTerminator NVARCHAR(5) = CHAR(13) + CHAR(10)
DECLARE #ColumnTerminator NVARCHAR(5) = CHAR(44)
DECLARE #FieldQuote NVARCHAR(5) = CHAR(34)
--DECLARE #FieldQuote NVARCHAR(5) = '"'
IF OBJECT_ID('[dbo].[Files_Temporary]', 'U') IS NOT NULL
DROP TABLE [dbo].[Files_Temporary];
CREATE TABLE [dbo].[Files_Temporary]
(
[ID] INT
, [FileName] NVARCHAR(255)
, [TableName] NVARCHAR(255)
);
INSERT INTO [dbo].[Files_Temporary] SELECT 1, 'MyFile.txt', 'MyfileA'
INSERT INTO [dbo].[Files_Temporary] SELECT 2, 'MyFile.txt', 'MyFileB'
DECLARE #Counter INT = 1
WHILE #Counter <= (SELECT COUNT(*) FROM [dbo].[Files_Temporary])
BEGIN
PRINT 'Counter is ''' + CONVERT(NVARCHAR(5), #Counter) + '''.'
DECLARE #FileName NVARCHAR(255)
DECLARE #TableName NVARCHAR(255)
DECLARE #Header NVARCHAR(MAX)
DECLARE #SQL_Header NVARCHAR(MAX)
DECLARE #CreateHeader NVARCHAR(MAX) = ''
DECLARE #SQL_CreateHeader NVARCHAR(MAX)
SELECT #FileName = [FileName], #TableName = [TableName] FROM [dbo].[Files_Temporary] WHERE [ID] = #Counter
IF OBJECT_ID('[dbo].[' + #TableName + ']', 'U') IS NULL
BEGIN
PRINT 'Creating new table with name ''' + #TableName + '''.'
IF OBJECT_ID('[dbo].[Header_Temporary]', 'U') IS NOT NULL
DROP TABLE [dbo].[Header_Temporary];
CREATE TABLE [dbo].[Header_Temporary]
(
[Header] NVARCHAR(MAX)
);
SET #SQL_Header = '
BULK INSERT [dbo].[Header_Temporary]
FROM ''' + #Path + #FileName + '''
WITH
(
FIRSTROW = 1,
LASTROW = 1,
MAXERRORS = 0,
FIELDTERMINATOR = ''' + #RowTerminator + ''',
ROWTERMINATOR = ''' + #RowTerminator + ''',
FIELDQUOTE = ''' + #FieldQuote + '''
)'
EXEC(#SQL_Header)
SET #Header = (SELECT TOP 1 [Header] FROM [dbo].[Header_Temporary])
PRINT 'Extracted header ''' + #Header + ''' for table ''' + #TableName + '''.'
WHILE CHARINDEX(#ColumnTerminator, #Header) > 0
BEGIN
SET #CreateHeader = #CreateHeader + '[' + LTRIM(RTRIM(SUBSTRING(#Header, 1, CHARINDEX(#ColumnTerminator, #Header) - 1))) + '] NVARCHAR(255), '
SET #Header = SUBSTRING(#Header, CHARINDEX(#ColumnTerminator, #Header) + 1, LEN(#Header))
END
SET #CreateHeader = #CreateHeader + '[' + #Header + '] NVARCHAR(255)'
SET #SQL_CreateHeader = 'CREATE TABLE [' + #TableName + '] (' + #CreateHeader + ')'
EXEC(#SQL_CreateHeader)
END
PRINT 'Inserting data from ''' + #FileName + ''' to ''' + #TableName + '''.'
DECLARE #SQL NVARCHAR(MAX)
SET #SQL = '
BULK INSERT [dbo].[' + #TableName + ']
FROM ''' + #Path + #FileName + '''
WITH
(
FIRSTROW = 2,
MAXERRORS = 0,
FIELDTERMINATOR = ''' + #ColumnTerminator + ''',
ROWTERMINATOR = ''' + #RowTerminator + ''',
FIELDQUOTE = ''' + #FieldQuote + '''
)'
EXEC(#SQL)
SET #Counter = #Counter + 1
END;
IF OBJECT_ID('[dbo].[Files_Temporary]', 'U') IS NOT NULL
DROP TABLE [dbo].[Files_Temporary];
IF OBJECT_ID('[dbo].[Header_Temporary]', 'U') IS NOT NULL
DROP TABLE [dbo].[Header_Temporary];
I've declared a variable, but neither the of both give me the correct result. The import is succesfull, but fieldquote is not ignored.
DECLARE #FieldQuote NVARCHAR(5) = CHAR(34)
--DECLARE #FieldQuote NVARCHAR(5) = '"'
I'm using SSMS V18.10

Just add one more setting like below to take care of double quotes.
It will work starting from SQL Server 2017 onwards.
SQL

WITH (
FORMAT='CSV'
