Best Uniques farming SSF strategy?

Haven't seen a Dyadian Dawn drop in the last 3 leagues, this time I wanna try to focus on getting one; also Unnatural Instinct and Stormshroud would be great, too.
Which atlas tree is considered the best for farming uniques?
I'm currently running full Torment/Rogue Exiles/Einhar/Expedition/Heist + Meticulous Appraiser keystone for extra rarity, no Eldritch altars because I'm spamming white maps only.
I may drop Heist which gives me nothing in maps (stocking up fully revealed gheists atm), if so which extra content should I choose?
On the left side we got Ritual and Blight, Strongboxes in the middle and Legion on the right side, dunno which one synergizes more with the other nodes...
Or would it be better to farm red maps (slower clear speed) and spec on Exarch altars?

Ty for inputs

Use Gilded Reliquary scarabs. They make a huge difference. I use Harvest to change all the scarabs I don't use into those when farming for my uniques.
