In the Board Editor you can pick a variant, but there's no 960.
960 is just standard with another starting position.
@MadNutella technically yes but you can castle in 960, while with board editor you can't castle if it's not a standard starting position, so they're actually different.
Oh, I overlooked that, thanks for letting us know!
@ericxyzhu there is actually an option in board editor to allow castling in other positions
@Funfinder15 oh sorry I didn't see that
The reason this even came up was actually a need to demonstrate/practice castling in 960, which can be very confusing at the beginning.
