[Question] Will bonuses to scarab drops on the Atlas tree affect Syndicate members in maps?

I know that the rewards of the Immortal Syndicate members in maps usually ignore quantity and rarity modifiers on the map/player. But will the modifiers to scarab drops on the Atlas skill tree affect their drops? (I'm asking about regular drops, not rewards from the bargaining option, which logically will ignore the nodes.)

Notably, since they are unique monsters, will the Significant Trove node give them 200% increased chance to drop scarabs or not?

Many thanks in advance (and my eternal gratefulness) to anyone giving me the answer.

Was wondering the same while designing my atlas for maximum scarabs (investing in scarab and rogue exile nodes). Read most of the available info on the Syndicate, but nothing related to their drops.
It does not look promising since they drop their stuff after your choice, but it will be tested on the release.
