Global suppression of shipping emails and re-triggering via API

Q1. If we were to globally suppress all shipping confirmation notifications/emails, can we still trigger it manually via API?

I’m planning to globally suppress shipping confirmation emails using this tutorial, which says:

How to disable the Order Confirmation or Shipping Confirmation emails**If you are using Shopify Plus:**Due to the importance of the both the order and shipping confirmations emails, Shopify does not give you the ability to deactivate these emails directly from your account, instead, they will turn these off for you. Simply reach out to Shopify support or your account manager in order to get approval to deactivate these notifications.

Then, trigger email notification via API by adding send_fulfillment_receipt=true.

Q2. Are there other ways to globally suppress shipping confirmation notifications/emails?

Thanks!
