Hello @Shemtar!
Currently their isn't a way to adjust the size of the of the delivery option on the Online Store. The only workaround I can think of is to create a modifier set of delivery options, so they choose it on your item. Then set the default delivery method to shipping - that way you still collect your customers address. If you use electronic delivery or pick up it won't collect this information.
If you still have questions please feel free to reach out!
