There's 3 Tesla superchargers between Vegas to Reno, in Beatty, Tonopah and Hawthorne, which is roughly 1/4, 1/2 and 3/4 of the way through. So definitely doable but definitely less convenient than an ICE car that can make that drive in one shot without refueling.
So stop in Tonopah NV,which is half way inbetween. Most EVs have the range to make it that far. I just picked that town by looking at a map - I'm sure there are a couple other choices even tough it is a desolate area.
I don't know if there is a charger there today, but it is an obvious place where one is likely to be added sometime.
