I don't see any MIRV options in the mod settings nor do I see any way to use it when I launched a MIRV. (Factorio version 0.17)

Possibly a mod conflict? I got Orbital ION Cannon installed but the problem persists if I disable that, I also got Rampant, Rampant Arsenal, Natural Evolution, LTN and a few other QOL mods.

The setting is in the 0.18 version

Ah alright, but how do I use it in 0.17 then?

Never mind, I'm dumb, I didn't realize the control units came back in the rocket silo so I was stuck at how to fire it.

Keep up the great work!
