This was done on the very first few days of Railjack, when nobody had any equipment, intrinsics, mods, nor knowledge of what's what - including DE, so the railjack itself was as useful as a brittle glass pea shooter.

TL;DR: Just park far away from everything and do the whole thing with either your archwing, or hop from crewship to crewship till everything's dead.
The run isn't anything special, but it's something that is very much doable, despite DE's lack of care for Solo mode.
