Give it a negative selling price, so high than no player will ever afford it?

Thinked about it. But this variant is ugly.

Feels like a waste of space to make a new attribute just for this.

Maybe I can filter out items with sell cost -1 from the list?

I feel a correct solution would be to unlock a research topic upon an item hitting base inventory.

EDIT  still I feel even that would be too much of railroading. but that's up to mod authors in any case.

EDIT2: it's not like one can't ruin a game in a thousand other ways. why pick this one for a fix and leave the others.
and if one fixes all of them, it's railroading and results in a boring slideshow.

In that case, he could use a research bounty from a mission... no need for an item at all.

Maybe @Nord wasn't aware of mission research bounties. I wasn't.

Well, research bounty allready applied to this mission. AND item. But now i think that best way is Bounty research, which allows to manufacture quest item.
