Off course, you can use the NoSQL database for IdentityServer4. Why not?
Here is an example with MongoDB
"initial plumbing" in the ConfigureServices () method in startup.cs.
public void ConfigureServices(IServiceCollection services)
{
...
services.AddIdentityServer()
.AddTemporarySigningCredential()
.AddMongoRepository()
.AddClients()
.AddIdentityApiResources()
.AddPersistedGrants()
.AddTestUsers(Config.GetUsers());
...
}
