I think you mean "divers."
And it's done through a combination of weight, breath control, and the amount of air in the boyancy compensator vest.
A nautilus uses gas-filled chambers in its shell to control its buoyancy.

The primary buoyancy control is by the mass of the equipment and weight-belt versus the diver's natural buoyancy and that of the suit; but divers also use an adjustable buoyancy jacket for fine control.

Buoyancy control is crucial for maintaining proper depth and position underwater while conserving energy. Mastering buoyancy control also helps protect aquatic ecosystems by minimizing damage caused by accidental contact with the reef or bottom. On the surface, good buoyancy control ensures safety and comfort during activities like surface swims or snorkeling.

No they cant really control gravity anyway...
The nautilus uses gas-filled chambers in its shell to control its buoyancy. By adjusting the amount of gas in these chambers, the nautilus can rise or sink in the water.
