Hi Lutz,
Apologies for the delayed response and thanks for explanation it a lot more clear now.
We are planning to proceed with parameter value snc/accept_insecure_gui =1 so it allows both types of connections secured and unsecured. We are going to perform the SAPLOGON configuration with SNC and push it to the user community.
For the few users who will be using non-SNC connections we will manually create the connection and allow them unencrypted until we find a solution. We have already signed a security variance with the internal security compliance team for few users until we find the solution to secure them.
Again, Thanks for your help.
Regards
Junaid
