I doubt it. They can try banning Telegram just like Russia did, but it clearly didn't work for the latter.
They can disrupt Telegram operations by financial sanctions, which is more efficient. Russia technically could do it too - Russian audience is not small, but they probably benefit from it a lot.
How so? Because they could prohibit Telegram in France?
They could seize the company
France cannot seize a company in the United Arab Emirates.
