Can I export excel data with UTF-8 without BOM?

Question

I export Microsoft Excel data by Excel Macro(VBScript). Because file is lua script, I export it as UTF-8. The only way I can make UTF-8 in Excel is using adodb.stream like t

Uf you prefer native T-SQL instead of external code

DECLARE @FILE_NAME              VARCHAR(255)    = 'd:\utils\test.xml'       --drive:\path\filename\
DECLARE @FILE_DATA              VARCHAR(MAX)    = 'test'            --binary as varchar(max)

DECLARE @FILE_NAME_TO           VARCHAR(255)                        --Temp name for text stream
DECLARE @FSO_ID_TXTSTRM         INT                                 --Text Stream
