Loading Delay Signed assembly with Assembly.LoadFile()

as part of our build process (as Post Build event in a project) I need to run a .net app that loads an assembly that is delay signed. This was OK when we had our own TFS server we could use sn -Vr to register assemblies for verification skipping.

However, when we moved to Azure DevOps we are getting exception, because we can't register assemblies for skipping via sn -Vr. Any way to get around this?
