Helm or Ring of infra vision would do the trick. They existed in BG 1. Was one of those useless items you dumped the second anything else came along. I don’t know if they exist in 5e though. Personally, I say let the humans suffer in the dark. They are humans and have garbage dark vision. With that said, I think Drow should probably have a disadvantage in the day.
Sunlight Sensitivity was in the game under Minthara's character sheet. It should be applied to any PC Drow characters as well.
It's no reason why Drow should have Superior Darkvision and then be able to fight outside perfectly in BG3.
But, but, Tadpole Magic!!!!!
I agree that it'd be nice if drow has sunlight sensitivity, but then playing as a drow would be an absolutely terrible experience in BG3's perma-daytime. Given that decision, PC drows losing their sunlight sensitivity trait is probably for the best.
