You don't need to map the member; you just need to map both types.

Given:

C#

namespace Db
{
    public class Order
    {
        public List<ShipOnly> Ship { get; set; }
    }
    
    public class ShipOnly
    {
        public string Name { get; set; }   
    }
}

namespace Dto
{
    public class Order
    {
        public List<ShipOnly> Ship { get; set; }
    }
    
    public class ShipOnly
    {
        public string Name { get; set; }   
    }
}

Initialization:

C#

Mapper.Initialize(cfg => {
    cfg.CreateMap<Db.Order, Dto.Order>();
    cfg.CreateMap<Db.ShipOnly, Dto.ShipOnly>();
});

Use:

C#

Db.Order source = new Db.Order
{
    Ship = new List<Db.ShipOnly>
    {
        new Db.ShipOnly { Name = "Test" }
    }
};

Dto.Order result = Mapper.Map<Dto.Order>(source);
Debug.Assert(result.Ship != null);
Debug.Assert(result.Ship.Count == 1);
Debug.Assert(result.Ship[0].Name == "Test");
