How to change function hint pkg.go.dev point to our own package server?

When mouse cursor stops over function, package, etc, documentation box is opened and there is a possibility to follow e.g. this kind of link

"`Println` on pkg.go.dev"

Is it possible to expand documentation on multiple server?

We have our own package server for private use, so how set documentation point to there?

Ideally linking own server first and if not found, then redirecting to pkg.go.dev.
