Is there a way to "fake" the ability maybe with a special attack or something? I can't figure out if there's a way to hard code "drop lowest" type mechanics.
Yeah, you just need to say in the weapon's description that you need to roll 2 d12s and use the higher roll for the damage roll. It's not currently implementable in DDB's coding. I also wouldn't use Advantage to refer to that, since advantage/disadvantage only apply to ability checks, saving throws and attack rolls.
Is it possible to set up a weapon that would give 2d12 drop lowest on damage for example?
It is not currently possible to alter a weapon’s base damage dice in any way.

The only way to “fake” it is to roll damage twice and only tell the DM the higher of the two results.
