Each ship has a cargo hold that you can dump stuff in. From the 2 ships I’ve been in (Frontier and Shieldbreaker) you can access the cargo hold from a computer to the left of the pilot seat. If you buy or find Ship Parts (the name of the item), you’d have to go to your characters Aid section, and move them to your ship’s cargo hold. Then the button shouldn’t be greyed out anymore.
I want to add that you can enter the cargo hold by going to the Menu (Tab on PC), then click on lower left where your ship is and see the cargo hold (F on PC)
You can also move things from the cargo hold to your inventory even if you’re outside of your ship, I don’t remember if you can do so the other way around.
