add_filter( 'woocommerce_checkout_fields', 'readonly_billing_account_fields', 25, 1 );
function readonly_billing_account_fields ( $billing_fields ) {
// Only my account billing address for logged in users
if( is_user_logged_in() && is_account_page() ){
$readonly = ['readonly' => 'readonly'];
$billing_fields['address_1']['custom_attributes'] = $readonly;
$billing_fields['address_2']['custom_attributes'] = $readonly;
}
return $billing_fields;
