My name is Lilith, I'm on the Social Care team at Shopify.
There is a way to do this. We've seen this question in the Community before and the solution in this post here is one of my favorite ones to recommend.
We also recently released a few different options amidst the current global situation. We have a full guide on how to set up your curbside pick up here.
Keep in mind in that last one that your shipping rate for local pick up will be set to Free and can't be changed.
Let me know how you do with the information above! I'm happy to answer any questions you think of as you work on your business.
