How is it implemented?

1. Magento\Config\Block\System\Config\Form::_initElement()

magento/magento2/blob/2.2.0/app/code/Magento/Config/Block/System/Config/Form.php#L369-L393


$isReadOnly = $this->getElementVisibility()->isDisabled($field->getPath())
    ?: $this->getSettingChecker()->isReadOnly($path, $this->getScope(), $this->getStringScopeCode());
$formField = $fieldset->addField(
    $elementId,
    $field->getType(),
    [
        'name' => $elementName,
        'label' => $field->getLabel($labelPrefix),
        'comment' => $field->getComment($data),
        'tooltip' => $field->getTooltip(),
        'hint' => $field->getHint(),
        'value' => $data,
        'inherit' => $inherit,
        'class' => $field->getFrontendClass() . $sharedClass . $requiresClass,
        'field_config' => $field->getData(),
        'scope' => $this->getScope(),
        'scope_id' => $this->getScopeId(),
        'scope_label' => $this->getScopeLabel($field),
        'can_use_default_value' => $this->canUseDefaultValue($field->showInDefault()),
        'can_use_website_value' => $this->canUseWebsiteValue($field->showInWebsite()),
        'can_restore_to_default' => $this->isCanRestoreToDefault($field->canRestore()),
        'disabled' => $isReadOnly,
        'is_disable_inheritance' => $isReadOnly
    ]
);

Details:

How is the is_disable_inheritance property used for a configuration field?

The ability to setup the disabled as and is_disable_inheritance properties is absent in Magento <= 2.1.3:

github.com

magento/magento2/blob/2.0.0/app/code/Magento/Config/Block/System/Config/Form.php#L350-L369


$formField = $fieldset->addField(
    $elementId,
    $field->getType(),
    [
        'name' => $elementName,
        'label' => $field->getLabel($labelPrefix),
        'comment' => $field->getComment($data),
        'tooltip' => $field->getTooltip(),
        'hint' => $field->getHint(),
        'value' => $data,
        'inherit' => $inherit,
        'class' => $field->getFrontendClass() . $sharedClass . $requiresClass,
        'field_config' => $field->getData(),
        'scope' => $this->getScope(),
        'scope_id' => $this->getScopeId(),
        'scope_label' => $this->getScopeLabel($field),
        'can_use_default_value' => $this->canUseDefaultValue($field->showInDefault()),
        'can_use_website_value' => $this->canUseWebsiteValue($field->showInWebsite())
    ]
);

But even in Magento 2.1.x >= 2.1.3 the $this->getElementVisibility()->isDisabled($field->getPath()) call is absent:

github.com

magento/magento2/blob/2.1.3/app/code/Magento/Config/Block/System/Config/Form.php#L388-L411


$isReadOnly = $this->getSettingChecker()->isReadOnly($path, $this->getScope(), $this->getStringScopeCode());
$formField = $fieldset->addField(
    $elementId,
    $field->getType(),
    [
        'name' => $elementName,
        'label' => $field->getLabel($labelPrefix),
        'comment' => $field->getComment($data),
        'tooltip' => $field->getTooltip(),
        'hint' => $field->getHint(),
        'value' => $data,
        'inherit' => $inherit,
        'class' => $field->getFrontendClass() . $sharedClass . $requiresClass,
        'field_config' => $field->getData(),
        'scope' => $this->getScope(),
        'scope_id' => $this->getScopeId(),
        'scope_label' => $this->getScopeLabel($field),
        'can_use_default_value' => $this->canUseDefaultValue($field->showInDefault()),
        'can_use_website_value' => $this->canUseWebsiteValue($field->showInWebsite()),
        'can_restore_to_default' => $this->isCanRestoreToDefault($field->canRestore()),
        'disabled' => $isReadOnly,
        'is_disable_inheritance' => $isReadOnly
    ]
);

2. Magento\Config\Block\System\Config\Form::getElementVisibility()

public function getElementVisibility()
{
    if (null === $this->elementVisibility) {
