Can I change the postage options after item has been listed?

Hi there. I am new to selling on ebay and have found myself in a confusing situation. I have listed an item as Postage Only, however, I was sent a message by a browser wondering if I could do Local Pick Up as they live around the corner. When I try to revise the listing of this item, the Posting Options won't allow me to change it to to Lacal Pickup. Does that mean I can't do Local Pickup?

G’day y”all,

It is 2023 I too have this problem… except I had inadvertently clicked free postage because you don’t pay for postage with local pick up. I have tried everything but to no avail. Now I can’t remove the FREE EXPRESS POSTAGE.   HHhheeeeppp
