In Laravel 5.6.25, you can use unsetRelation():
在 Laravel 5.6.25 中，您可以使用unsetRelation()：
$product->unsetRelation('merchant')->unsetRelation('picture');
Before that:
在那之前：
$relations = $product->getRelations();
unset($relations['merchant'], $relations['picture']);
$product->setRelations($relations);

I have to tables with the same fields.. So I need to check the different column based on value. So if the value of foreign key is same then need to unset that relation
我必须使用相同字段的表..所以我需要根据值检查不同的列。因此，如果外键的值相同，则需要取消设置该关系
If you have merchantproperty in the model (merchantcolumn in the table) you can get it value using $product->getOriginal('merchant')or $product->getAttribute('merchant')
如果merchant模型中有属性（merchant表中的列），则可以使用$product->getOriginal('merchant')或$product->getAttribute('merchant')
