Cant Disable Lazy Loading and Proxy Creation on DbContext EFCore

Is there a way to disable lazy Loading on EntityFramework.Core

In my previous code I have done the following :

  public DataContext(string nameOrConnectionString) : base(nameOrConnectionString)
    {

        Configuration.LazyLoadingEnabled = false;
        Configuration.ProxyCreationEnabled = false;
    }

but now using the new ef 7 i cant find any option to do so

public DataContext(DbContextOptions<DataContext> options) : base(options)
    {
        //should have been in the options
    }
