I do not think so. Did not you mean a compile time flag for OpenSSL?

I pushed a few FIPS-related patches between 1.4.2 and 1.4.3:

The basic idea behind those patches is to return a failure if a non-FIPS
algorithm (such as MD5) is requested by the application. So libssh2 should
no longer crash on its own. Still you need to handle these failures in your
application in order not to crash anyway.
