The Technomancer

This is a story related achievement that can be obtained in Chapter 3 during the main quest to gather allies. I will try to be as spoiler free as possible. Save before approaching any potential ally as gaining support of some exclude others and acquiring 3 ends the quest.

Go to Anton Rogue in the Ophir Slums. My relationship with the Vory was hostile so he would not simply give me support. I was, however, able to buy his support for 500 serum which unlocked the achievement right away. I am not certain but aligning yourself with the Vory might exclude you for gaining Noctis merchant support
