Can I disable RC4 in favor of a stronger Cipher

I'm deploying ArcGIS for Server 10.3.1 in a secure Enterprise environment.  A recent scan showed we had the RC4 cipher enabled, and being used on Port 6443.  We use the Web Adaptor, and the firewall blocks all in/out 6443 traffic, but my life would become substantially easier from a documentation and risk acceptance standpoint if I could configure the server to use TLS with 3DES or another stronger cipher.  Is it possible to configure this somewhere in the ArcGIS settings?

 

I tried flat-out disabling RC4 before, and it broke the server.  I began to get SCHANNEL errors saying I didn't have a cipher available to establish the connection.
