telegram uses proprietary encryption, so the answer is no.

Why not use custom application builder and try building the application if that is not available natively in CP

This is quite likely not possible given HTTPS Inspection would be required and the app will break due to Certificate Pinning.
You could use rate limiting to severely limit the speed of any Telegram connection, thus making any file transfers slow (might also impact calls over Telegram as well).

Yes - obviously after HTTPS inspection else this would not work. I by default assumed that HTTPS inspection is on

I would recommended to block the complete Telegram application on the firewall.

Since HTTPS inspection is not possible. It is not waterproof but it should work in theory.

Also I am wondering if you still want to use Telegram on a work environment. But maybe that is more a political discussion.
