any ideas of how funerals work these days cause of covid?

my sister just died and she lived in brooklyn, my brothers wont go to the funeral thanks to covid, and i dont want to go alone. even if i were to go do they still do funerals, or do they bury people privately and then you cant go to it, i wouldnt want to fly down there and find out thats the case. i know they have limits , any ideas?
