As far as i know, no.

Unless you are forceing all clients to use SSLv2 only (since that doesn't support renegotiation). 
Are you sure you want to disable it and not just prevent old clients from 
using the vulnerable renegotiation methods? If it's the last
you'll need to upgrade to 2.8+ to get access to tls_disable_workarounds. 

you have 2 problems. 
- One is the vulnerable methods 
- the other is renegotiation is considered a denial of service vulnerability.. 

You really dont have any option to upgrade.. 
Whats the os your running?
