Canids Cradle Conundrum

So I’m tearing up Monarch, and when I met Graham, I followed the quest objectives for the extra exp, even though I know Zora was right.

Fast forward to the CC module, and I want to broker peace with MSI and the Ionoclasts, but Zora won’t talk to me because I didn’t do Sucker Bait.

Can I complete the objectives of sucker bait without actually being assigned it, and still broker peace, or am I stuck choosing one or the other? Cause if I choose one, it’s not going to be Graham and Zora.

Anyone else have this issue?

Edit: stealth killing Graham does not work. Zora says the Iconoclasts are too on edge to do it. Guess they have to die?
