NCM - how to force SSH version

NCM - how to force SSH version

Hi,
 NCM 12.0 installed on a linux OS, i have some device in inventory to backup the configuration and those devices don't support SSH version 1. The problem is that NMC try to connect with SSH version 1 as a first try and i suppose that the connection exceeded the timeout.
Is there a way to force NMC to use SSH version 2? Maybe to change the priority so that the first try is done with SSH version 2.

Regards,
Christian
