Different Ship To and Billing address on Guest check-out?

Magento 2.4.2-p1
Smartwave Porto theme
all extensions from Amasty

We are switching from Magento 1.9.4 to Magento 2.4.2-p1. We do local gifts delivery and I just noticed that during the Guest check-out, there is only one address = SHIP TO (which we renamed to ‘Delivery address’). The problem with this is that most all of our customers will be sending a present to someone else so the Delivery (Ship to) and Billing address will be different (they will be paying for a gift for someone else which will go to the person’s who is getting the gift address).

How best to change this?
