I think however OP is correct that in assuming such a link exists, then an intelligent agent will trend towards preserving its own agency while also preserving its own existence.
That said, I am a skeptic when it comes to intelligence. The term is fraught and IMHO not a helpful term in science nor philosophy. We are better off simply defining intelligence in anthropocentric terms and claim no non-human system can become intelligent by definition. I would even go further, given how much racist pseudo-science the quest for explaining intelligence has produced, we are better off abandoning the term entirely.
However, the pressures on an artificial system are quite different. Its replication depends on successfully doing the jobs its creators put it to and, especially if said creators have done their job, little to nothing else. Inventing goals for itself is not adaptive here (unless the system's creators do a catastrophically bad job, which I'm not ruling out).
