Drupal Commerce "Add to Cart" form allows setting "hide_form" parameter on form_state to hide the cart form.
This is helpful and an alternative to setting #access = FALSE; directly.
In commerce_cart's class AddToCartForm it's implemented like this:
// The widgets are allowed to signal that the form should be hidden
// (because there's no purchasable entity to select, for example).
if ($form_state->get('hide_form')) {
$form['#access'] = FALSE;
}
This is the complete AddToCartForm.php implementation:
/**
* {@inheritdoc}
*/
public function buildForm(array $form, FormStateInterface $form_state) {
$original_form = $form;
$form = parent::buildForm($form, $form_state);
/** @var \Drupal\commerce_order\Entity\OrderItemInterface $order_item */
$order_item = $this->entity;
// The widgets are allowed to signal that the form should be hidden
// (because there's no purchasable entity to select, for example).
if ($form_state->get('hide_form')) {
$form['#access'] = FALSE;
}
else {
$selected_variation = $form_state->get('selected_variation');
// If the order item references a different variation than the one
// currently selected, and the selected variation is supposed to use
// a different order item type, rebuild the form.
if ($selected_variation && $order_item->getPurchasedEntityId() != $selected_variation) {
/** @var \Drupal\commerce_product\Entity\ProductVariationInterface $selected_variation */
$selected_variation = $this->entityTypeManager->getStorage('commerce_product_variation')->load($selected_variation);
if ($selected_variation->getOrderItemTypeId() !== $order_item->bundle()) {
/** @var \Drupal\commerce_order\OrderItemStorageInterface $order_item_storage */
$order_item_storage = $this->entityTypeManager->getStorage('commerce_order_item');
$order_item = $order_item_storage->createFromPurchasableEntity($selected_variation);
$this->prepareOrderItem($order_item);
$this->setEntity($order_item);
$form_display = EntityFormDisplay::collectRenderDisplay($order_item, $this->operation);
$this->setFormDisplay($form_display, $form_state);
$form = $original_form;
$form = parent::buildForm($form, $form_state);
}
}
}
return $form;
}
I think it would make sense to have the same functionality in commerce_variation_cart_form?
It doesn't seem to be inherited / called, at least nothing happens, if I alter the commerce_variation_cart_form and set the value accordingly. Only setting #access = FALSE; works.
Implement the same logic as in commerce_cart

Sure. Patch or MR? Otherwise I'll get to it next time I touch the module (which may be a while).
Thanks @John Pitcairn, no pressure. I saw that yesterday and thought it would make sense to open an issue to align this with commerce. But setting #access on &$form directly is a viable solution, so this is just a nice to have.
