How to configure Apache to use a specific cipher mode in SSL mode?

I know how to configure apache to use a specific cipher, say AES with RSA key exchange algorithm, simply I should add this to "httpd.开发者_高级运维conf" file:

SSLCipherSuite AES+RSA

But AES has different modes of encryption such as CBC, CTR and ECB. How can I enforce Apache to only use CTR mode (assume it is already enabled in Openssl).

I really appreciate any thought on this

Thanks
