For Nevada it looks like Republicans are crushing Dems at in-person, so far, but that could just be due to how Nevadans are. If most Dems are in Clark County and most Clark County Dems have unusual work schedules they might not behave like others in other states, so I wouldn't read too much into that.
EDIT:
Yes, it looks like historically Republicans are more active at in-person early voting in Nevada

248k Rep to 165k Dem
Whereas for Mail Ballots the Dems crushed Reps 631k to 356k (if I'm reading this right)

Election Day was 60k Rep to 44k Dem, so it seems that in Nevada overwhelming majority of the state uses mail/dropoff ballots, a sizeable minority uses in-person early voting, and about 100k people vote in-person on election day.
