I would like this option too (disable the option of entering a different address).Nowadays, too many people try to scam.checking the time, this has been posted for four years. Could Shopify tell us the answer without answer something else.   

I am using Crave theme. So that I am following steps for sectioned themes. However, I can't find  theme.js or theme.js.liquid under the my code. I am able to input the check box but not function. Please help.
