You could solve this by using Laravel's accessors and mutators.
In this example I am only going to add gender from UserDetail because I am lazy. So we start with adding a accessor for gender in our User model
public function details()
{
return $this->hasOne(UserDetail::class);
}
public function getGenderAttribute()
{
return $this->details->gender ?? null;
}
This getter will get the gender from the details or null if no details exist.
Now we add a new field to our User resource in Nova.
public function fields(Request $request)
{
return [
ID::make()->sortable(),
Gravatar::make(),
Text::make('Name')
->sortable()
->rules('required', 'max:255'),
Text::make('Email'),
Password::make('Password'),
Text::make('Gender')
->rules('required'),
];
}
Going to the create user form, it will look something like this:

Of course this will not make it save it, as it has no idea how to handle the gender field. For handling this we override fillFields method.
protected static function fillFields(NovaRequest $request, $model, $fields)
{
// Get all of our user details data
$userDetails = $request->only(['gender']);
// Remove them from the request
$request->request->remove('gender');
$result = parent::fillFields($request, $model, $fields);
// Insert them in the details object after model has been saved.
$result[1][] = function () use ($userDetails, $model){
$model->details()->updateOrCreate(
[],
$userDetails
);
};
return $result;
}
Now we are able to see the gender field as a normal field on the user, and have no need for the UserDetail resource. To add more fields to be saved in the user details table, we have to add them to our only and remove them from our request. (would make sense to have that in a array)
This method also works when updating a user because we choose to use updateOrCreate.

A extra note about this approach is that we just introduced a n+1 query, as we are lazy loading the details relation when trying to get the gender attribute. To solve this we simply override indexQuery and add details to the query builder.
public static function indexQuery(NovaRequest $request, $query)
{
$query->with('details');
return parent::indexQuery($request, $query);
}
