How to add or update Identity Provider details without restarting the app?

I'm using .NET 4.6 with OWIN Context to configure app security. The app supports multiple identity providers, which I'm adding in the Startup.Auth.cs file like this:

private static void AddOidcProviders(IAppBuilder app, IEnumerable<IdentityProviderDetails> allProviders)
{
    var oidcProviders = allProviders.Where(x => x.ProviderType == IdpProvidersConstants.OpenIdConnect);
    foreach (var oidcProvider in oidcProviders)
    {
        app.UseOpenIdConnectAuthentication(
        new OpenIdConnectAuthenticationOptions
        {
            //provider specific config
        });
    }
}

The problem with the code above is that it runs only once - during the app start-up. Since I keep those providers details in the database, they can change unexpectedly. Is it possible to add more providers and/or update existing ones without restarting the app pool? I've tried injecting AppBuilder to HomeController and re run the AddOidcProviders, but the providers details are not updated.
