Just came across this on reddit. It's a runway 1R instrument approach at KSFO in the PMDG 777, but I see no available 1R instrument approaches in the sim's navdata (Asobo's or Navigraph's) or in the PMDG 777's. This must mean that customizing the PMDG 777's navdata is possible.

Interesting!

I remember adding in custom restricted RNP waypoints to the PMDG navdata for the original NG 20 years ago.

Yeah, I've seen others do this as well. The 777 uses the newer navdata format which is just a big database, instead of those small individual text files, though. Similar to the Fenix A320, except I haven't found a way to add approaches in the Fenix navdata yet.
