Magento 2 how to remove update button from checkout billing address

We have 2.4.5 magento version.

how can we remove “update” button from billing address and allow to placer order. we have virtual product so in virtual product we do not need to add shipping address we just need to add billing address but client want to remove “update” button for update billing address.so they want to update billing address without click on update button.

Thanks
