Im running M2 2.3.4 and would like to disable the add to cart bottum on some product pages because they are to complicated to ship.

Have created an Yes/No attribute "afhentes" and I would like to disable the add to cart by enable this attribute.
One the same time I would like a text displayed indsteed: "Pick up in store"

Have found some around the net but they does not seem to work.

Hope someone can help med out with this matter.
