Has the Maldives been submerged?

No, it is said that there is still 50 years to turn around for you. In fact, the Maldives is a country composed of multiple islands. It has not been completely submerged yet, but many islands will definitely become unfit for habitation and tourism due to rising sea levels. There is also a more important issue. Rising sea temperatures will cause coral bleaching and death. If you can go early, you must go early. This can't wait.
