I worked on this a while back in parallel. You can dump Apple's entire database in ~2 weeks. Around 3 billion records including China.
You can compress it down to only a few gigs and have everything offline. I also got a ichnaea proxy though not as well tested. Been using it myself and it's alright,
How would I enable it?

Seriously. How did you even install GrapheneOS without a little bit of self-determination?
It's not immediately obvious what I need to enable in order to get better location services, if it's already enabled, and whether the feature in the linked post even helps with the issue. Why are you so hostile?
I use Graphene for privacy without a massive hassle, I don't care enough about my phone ecperience to be really into it, I just want provacy. And generally GrapheneOS has been GREAT for this.
