✅

You can use to_representation to override the serialization. You can then remove the entries with None value.

class ProfileProductsSerializer(serializers.ModelSerializer):
    video_product = VideoProductSerializer(read_only=True)
    image_product = ImageProductSerializer(read_only=True)

    class Meta:
        model = ProfileProduct
        fields = ['id', 'video_product', 'image_product']

    def to_representation(self, instance):
        data = super().to_representation()
        return {k: v for k, v in data.items() if v is not None}
