[2019] Altering Valguero's Broodmother to unlock Tek Replicator?

I've been searching around trying to find out how to edit the Broodmother on Valguero to unlock the Tek replicator upon defeat but I just haven't been able to find any useful information. I even downloaded the beacon app as it promised that it would be able to edit any loot drop and I had seen someone in the steam forums say you could use it for this but the user interface for beacon is so unintuitive it hurts. even if someone can tell me the basics of editing a boss's tek engrams I can take it from there, I just have no idea what .ini commands would 1) alter a creature's loot drop and 2) drop an engram as loot instead of a blueprint.
