A website's ability to query for payment methods must be disabled.
This setting determines whether websites can check if the user has payment methods saved.
If this policy is disabled, websites that use "PaymentRequest.canMakePayment" or "PaymentRequest.hasEnrolledInstrument" API will be informed that no payment methods are available.
If this policy is enabled or is not set, websites can check to determine if the user has payment methods saved.
