Trying to Limit Package installation for Enterprise with Signing Packages

There seems to be alot of potential dependencies that need to be signed, if someone has a well currated NuGet.Config file I could use or an alternative to adding each dependency in one by one that would be really helpful.

If someone happens to have a good alternative to limiting package installation by the end users that would be great, we are looking to limit it to gold certified packages or potentially just Uipath published packages but it seems that the Signing would be pretty tedious.
