Is it possible to show local pickup for products only in stock?

[yoonlaser]

I have a shopify store and the theme I use is the enterprise theme. I also added one manual payment method called 'local pickup - pay at pickup' in addition to the default payment options such as credit card and Paypal payment options. if I want to show the manual payment option, 'local pickup - pay at pickup' to only orders containing only in stock items, how can i implement that? I'm using the shopify advanced plan.
