Answer

step 5 : app/code/Enrich/Package/view/adminhtml/web/products/custom_validation.js in side js file add validation 
      validator.addRule(
                'validate-bonus-calc', function (value) { 
                    var packageType = $('select[name="product[package_type]"] option:selected').val();
                    var bonus_calc =  $('select[name="product[bonus_calc]"] option:selected').val();
                    if (packageType==2 ) {
                        return true;
                    }
                    if(packageType==3 && bonus_calc!=="") {
                        return true; 
                    } else {
                        return false;
                    }
                }, $.mage.__('This is a required field.')
            );

" > step1- if attribute is required = true in upgradeData.php . then need required = false and change the version
step2 - In mudule.xml  file set the version as in upgradeData.php.
step 3 - create app/code/Enrich/Incentive/Plugin/Product/Validationrules.php file wire the code 
<?php
namespace Enrich\Incentive\Plugin\Product;

use Magento\Catalog\Ui\DataProvider\CatalogEavValidationRules;
use Closure;
use Magento\Catalog\Api\Data\ProductAttributeInterface;

class Validationrules
{
    public function aroundBuild(
        CatalogEavValidationRules $rulesObject,
        Closure $proceed,
        ProductAttributeInterface $attribute,
        array $data
    ){

$rules = $proceed($attribute,$data);
        if($attribute->getAttributeCode() == 'bonus_type'){

$rules['validate-bonus-type'] = true;
        }
        if ($attribute->getAttributeCode() == 'bonus_calc') {
            $rules['validate-bonus-calc'] = true;
        }
        if ($attribute->getAttributeCode() == 'bonus_value') {
            $rules['validate-bonus-value'] = true;
        }
        return $rules;
    }
}

step 4- config plugin in di.xml
<type name="Magento\Catalog\Ui\DataProvider\CatalogEavValidationRules">
        <plugin name="Enrich\Incentive\Plugin\Product_extension_product_attribute" type="Enrich\Incentive\Plugin\Product\Validationrules"/>
    </type>
