From what I hear, there are all kinds of in-person events in NYC around the auction which are free. Given the dismal Covid social life of the last 18 months, if I was in or near NYC, I would be jumping on that shark and riding it in person, in a mixed metaphor kinda way.
There is info on the artists at journal.burningman.org, probably other official sources, and in the press. Anyone, buyer or not, might enjoy reading the artist websites, bios, look at their other work, their life story, and their exhibition history. It is a skill to learn to research an artist whose work you are attracted to.
