You need S+ for that, use the Mutator to swap the gender. Mate boost works, but don´t try to breed them because you won´t get an egg, gestuation just ends with nothing.
If you want to breed them you have to use the S+ Propagator, works like a charm and also mutations (but no color since indom has no regions).
You´ll need element though for both the Mutator and the Propagator to use.

how do i get S+ ?

It's a mod, you have to install it and use it.

If you use the mutator pulse to enable mating on dinos that can't mate after making one of them male then they will give birth to a live baby. I'd be ready to cryo it quick though to put in a raising pen as the babies made this way still randomly enrage.

@Samdragontear
That is why I use Dino Storage V2 as soon as the baby Indom makes it's appearance I pop it into a soul trap, and then let it hang out with an S+ Nanny in a raising pen so I don't have to worry about being eaten when I try to imprint the little bugger

whats the spawn code for it

You CAN get it through pure willpower and effort, though it's a very low chance. I use a mod such as S+ for the mutator or Pugnacia for the gender swap potion.
