If anything can be said about the breakdown of mail-in ballots vs in-person voting it is that the former favours Biden. NV is likely to be a bit more balanced, but in no instance so far has a vote total moved towards Trump (dems told people to vote early by mail and a lot of what remains to be counted is from large urban districts that trend Democratic.)
