Can you show your storable model please ?
Why do you say conditionaly ? I don't see any condition to load the relationship.

How do I conditionally load nested relationship?
$warehouseToBeLoaded->slots->load([
'storable',
'storable.rewards'
]);
I have the above code to load relationships of a model instance. As you can see I'm also loading a nested relationshio storable.rewards but storable is a polymorphic relationship and some types of storable don't have rewards relationship and this causes my query to fail with the below error:
Call to undefined relationship [rewards] on model [App\\Models\\Crop]
How can I conditionally load storable.rewards relationship? What would be the most SQL-wise efficient?

With a WHERE or if relations are setup, this section gives examples:

And see https://laravel.com/docs/12.x/eloquent-relationships#has-many-through
