How to refresh assemblyBinding information loaded from app.config from another app.config file?

Dependent Assembly is being resolved to the wrong version and I need to use another app.config file with different assemblyBinding information.

I used other posts to change the config file with code like this:

AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", assemblyFolder + @"\MRPDataIntegrity.dll.config");
System.Configuration.ConfigurationManager.RefreshSection("configuration");
//the rest of refresh code from other posts

This doesn't affect though assemblyBinding information because i still get exception. I do not want to resort to this solution:

 AppDomain.CurrentDomain.AssemblyResolve +=..

Is there a hacky way to access and/or modify assemblyBinding information preloaded into application?
