Please expose an option to configure the field delimiter for CSV export. I want to set semicolon as field delimiter instead of a comma.

Internally the Grid uses SpreadStreamProcessing library to perform the export. That said, a necessary prerequisite to implement the current enhancement is that SpreadStreamProcessing supports settings for changing the delimiter when exporting to CSV. You may vote for the item and follow it to get status email updates.
For the time being, you may customize the exported file to set the desired field separator as suggested in the Grid CSV export - change the comma field delimiter knowledge base article.
