How can you revoke a client certificate with Eventgrid MQTT broker

I have created an MQTT enabled namespace in event grid and uploaded self signed CA certificate for client authentication. However, if i want to revoke one of the client certificates, I did not see an option for that.

If the service does not support this, then other option would be through a CRL distribution point. I tried hosting crl and add the url in signed certificates from this CA but still connection was succeeding for a revoked certificate.

Is there any way to achieve this?

Also any sdk support for this broker feature?
