Picocli: is it possible to calculate Option default value with help of some other Autowired field?

I want to implement the following logic of Option default value calculation

@Command(name = "test-command")
public class TestCommand implements Callable {
    
    @Autowired
    DefaultValueUtils utils;
    
    @ArgGroup
    EntityGroup functions = new EntityGroup();
    
    class EntityGroup {
        @Option(names = "--function1", defaultValue = "true")
        boolean function1 = utils.isFunction1();

        @Option(names = "--function2", defaultValue = "true")
        boolean function2 = utils.isFunction2();
    }
    
    ...
}

I have 2 boolean options - function1 and function2; if they are not provided their default values are specified in some other place. But if options provided, I need to override values with provided ones. One more problem is in following logic:

if none of them provided - default values should be calculated; If one of them provided - only provided one is true, not provided false; If both provided - both are true

How can I implement this?

This current block of the code is failing because utils is null during EntityGroup instantiation.
