No — if you read what Isabella and Ferdinand wanted to do, the primary reason was going after the Muslimes. Later generations yes went after the gold. The initial aim right from Henry the Navigator of Portugal was anti-Islamic. Vasco de Gama and the other Portuguese attacked Muslime concerns in E Africa, the Arabian peninsula and W. India
That had to do with liberating Spain from the Moors, not with colonizing other parts of the world in order to spread Christianity. No one tried to convert Muslims because that was futile.

That all goes back to the Muslism presence in the Iberian peninsula (Spain and Portugal) and the struggle to free it from the Moors. Unlike the Holy Roman Empire and the northern countries, southern Christians deal mostly with Muslims intrusions and were therefore engaged in a protracted war against Muslims. But the aim of explorations of the New World was motivated by trade, economy and spices, not spreding Christianity as its primary goal. That was an assumed collateral.
