This was never possible as Ivran never matched the requirement for the 'two elves' quest, not in the old version nor in the current version. You best bet may be to just edit this code in exploration.gd and replace "Dark Elf" with "Tribal Elf".
func shuriyaslaveselect(stage):
if stage == 1:
main.selectslavelist(true, 'shuriyaelfselect', self, 'person.race == "Elf"')
else:
main.selectslavelist(true, 'shuriyadrowselect', self, 'person.race == "Dark Elf"')
