The scene is:

When displaying the tel field in a Users table in the foreground, the last 4 digits of the phone number are replaced with *.

The method I use is:

class User extends Model
{
    public function getTelAttribute () {
        return substr($this->attributes['tel'], 0, 7) . '****';
    }
}

If you write it like this, it will generally be fine.

However, when the user modifies personal information through the form, the phone number displayed in the input is

Example: 1391234**

What I want to solve is:

In the case of using the reader (getAttribute), how to
temporarily cancel the action to the reader (getAttribute) under certain conditions, so as to display the complete phone number?
