Turn off orders at a certain time

Site URL: https://www.sundogbread.com/preorder

Hi! Is it possible to turn off ordering for all products within a category at a specific time? We are a market bakery that turn off online orders at 10am twice a week, Wednesday (category) and Friday (category). Right now I am manually changing the inventory to 0 for those items, so anything that will be less time consuming will be helpful. 

You can use CSS to remove all add to cart button on Preorder shop page

Add this code to Pre order page header (Hover Preorder on Not linked or Main Navigation > Click Gear Icon > Advanced)

<style>
  .sqs-add-to-cart-button-wrapper {
    display: none !important;
}
</style>

You can prevent customers from adding products to the cart by hiding the 'Add to Cart' buttons (as suggested above) but be aware of one limitation. It won't prevent customers from checking out with any goods they've already added to the cart.

Products remain in the cart indefinitely unless goods are removed from sale (products deleted or stock zeroed) so the only foolproof way to prevent purchase is to set the inventory to zero - as you are doing already.
