The only Adagio program that currently allows defining the Excel Table layout style when exported with ExcelDirect is GridView.
The information regarding directing ExcelDirect to a different (non-Excel) output and other related material can also be found on a
tech tip on our website. There is a facility to specify the Computer Name for determining which users get this behaviour, but I'm guessing your RDP requirements precludes this configuration.
You request has been forwarded to R&D. I imagine if this was to be set at a user-level, it would have to work not only for RDP but also the Cloud.

I see back in 2010, this section was made available to add to the SSI2XL.INI file, and not yet documented in the tech tip above. But again, I presume that using RDP precludes the user of the <windows user name> in this feature usage.
To turn off the creation of Excel 11 tables use
[DisableTableCreate]
<windows user name>=1
