I want to remove the “Ship to a different address?” checkbox from the WooCommerce checkout page, but I am encountering an issue with the checkout calculations.

Here’s the scenario:

• I want to keep the “Ship to a different address?” functionality checked by default (always using the shipping address for billing).
• When I remove the checkbox using a WooCommerce hook like remove_action, the JavaScript logic in checkout.min.js treats the checkbox as unchecked.
• As a result, WooCommerce uses the billing address for calculations instead of the shipping address.

Currently, I’ve modified the checkout.min.js file to always consider shipping fields in the update_checkout_action function:

update_checkout_action: function (o) {
    var r = e("#shipping_country").val(),
        c = e("#shipping_state").val(),
        i = e("#shipping_postcode").val(),
        n = e("#shipping_city").val(),
        a = e("#shipping_address_1").val(),
        u = e("#shipping_address_2").val(),
        d = r,
        s = c,
        m = i,
        l = n,
        p = a,
        h = u;

    var g = {
        s_country: d,
        s_state: s,
        s_postcode: m,
        s_city: l,
        s_address: p,
        s_address_2: h,
        // other data...
    };
    // ajax call...
}

This modification works as expected. However, I want to avoid modifying the core checkout.min.js file.

A way to hook into WooCommerce to remove the checkbox (#ship-to-different-address) from the DOM.
Ensure that WooCommerce calculations still use the shipping address, even if the checkbox is removed.
Avoid modifying the core WooCommerce files.

Is there a way to achieve this using hooks, custom JavaScript, or another clean method?
