Product variant validation remove price validation

I followed doc here Customizing Validation — Sylius documentation
and found it’s outdated, my sylius version is 1.9.8
i found i need to remove one section in file
vendor\sylius\sylius\src\Sylius\Bundle\CoreBundle\Resources\config\services\validators.xml

but how do i override this file , which directory and which file name should i put the overriding file validators.xml ?
