                'user_defined'          => true,
                'position'              => 999,

        $customerCLV = $this->eavConfig->getAttribute(Customer::ENTITY, 'customer_amnt');
        $customerCLV->setData(
            'used_in_forms',
            ['adminhtml_checkout',
                'adminhtml_customer',
                'adminhtml_customer_address',
                'customer_account_edit',
                'customer_address_edit',
                'customer_register_address']
        );
        $customerCLV->save();

Answer 1

Note: I have checked the code in Magento version 2.2.4.

The Personal Information section under the Customer View tab comes from the /vendor/magento/module-customer/view/adminhtml/templates/tab/view/personal_info.phtml file, which gets the required information from it's block file /vendor/magento/module-customer/Block/Adminhtml/Edit/Tab/View/PersonalInfo.php.

If you want to show some information in this section, you need to override the block file first and write the custom function to return the required data.

Below is an example:

I wanted to show gender information. So content added to my phtml file:

<tr>
    <th><?= $block->escapeHtml(__('Account Lock Expp:')) ?></th>
    <td><?= $block->escapeHtml($block->getGenderInfo()) ?></td>
</tr>

and the content of my custom function:

public function getGenderInfo() {
    return $this->getCustomer()->getGender();
}

I hope it is clear now.
