System Director at DAG. What kind of certificate? (Fallout 4)

In General Atomics Gallery, you need to report to this director - a robot, but he, an infection, constantly requires a certificate and then aggravates. I can't persuade him, I tried all the dialogue options, no, he rests on this certificate. I would like to resolve the conflict peacefully. On the other hand, if this certificate does not exist at all, then to hell with it, I'll just tear it apart from this director. But on the other hand, if this certificate lies somewhere in nearby buildings, then, of course, you want to find it. In general, tell me (without unnecessary spoilers). Will I find this certificate if I thoroughly screw all the buildings into General Atomics? (I kind of climbed superficially but did not find it). Or is it I stumbled upon a piece of some kind of quest and then wandering around the world I will find this quest or someone who will give me this certificate? (in this case, I will leave the quest for now). Or, you just need to shake this director. he is making a mistake and there is no identification? Let me remind you that a peaceful solution to the issue is preferable. And, please, do without spoilers, but with answers like: (ID is somewhere nearby, look for it; this is someone's quest and then you will get on it in the future; or: there is no ID - just urinate him).
