Assuming they have any individuality at all, that they are merely "not-humans", perhaps.

I do strongly suspect that one of the Fermi paradox's great filters, however, is abandonment of life's primary modus operandi of infinite growth, including the way it has manifested in our economics.

Biological immortality, or at least extreme longevity, likely comes before interstellar colonization, if our own example is to be taken as any indicator. That forces a population cap in and of itself, which in turn caps all other industrial needs, which in either case, become increasingly efficient, barring something like the self-destructive modern political backlash that seeks to undo that general trend for the sake of marginally increased profits.

Should a civilization fail to make that accounting, and continue that biological tendency at growth at all costs, it will likely exhaust its own resources before it takes on the considerably resource intensive task of spreading beyond its biosphere.

If it succeeds in that fundamental change, it's galactic footprint will be minimal. There would be no motivation for such a civilization to colonize more worlds of sufficient spread than would cement its collective survival against any potential cosmic disaster. Similarly, there would be no need for megastructures to provide power for an ever-growing and ever-more-hungry population. So each would only spawn three or four such pockets of self sustaining populations in the galaxy, each with an industrial footprint practically invisible from any real distance.

Or, alternatively, tyranids.
