Pay In Store available only for In-Store Pickup

Hello every one,
I have two problems that I need to solve.
1. Like the tittle topic, I want to config plugin Pay In Store available only for In-Store Pickup.
2. In my shop, I have many items out of stock, but I want customers to order items that are out of stock.
How can I do that?
Thanks you

1. Create a new payment method. You can copy Cash on delivery payment plugin and change file/class names and namespaces. In payment processor class, you will find HidePaymentMethod method. Return true if Pick-up in store is not selected.

2. Go to product edit page, expand Inventory tab and then set Inventory method as Don't track inventory.

You got to have that here in HidePaymentMethod:

And those services in the constructor:

Never mind the above, use these:

Or, use Payment Director ;)
