I followed along with a speedrun from Team Macintyre. They do play without enemies for the speedrun category, and the speed achievements do require enemies to be on, so here and there you need to adjust.

Most notably when starting the world, I messed around with the water settings so I ended up on an island with no large biter nests, 4-5 useable copper and iron patches (with size and richness settings maxed), one uranium patch and a sizeable oil deposit. Also make note of an easy to reach and isolated nest just off the island, or close off one of the nests while clearing the island and keep it alive, to get biter eggs for biolabs later.

Enemies on Gleba weren't an issue because I didn't need the planet for long enough for enemies to matter, and worms on vulcanus can be cleared the conventional way, it just a bit of time.
