OR

You can download the module from github link https://github.com/jothibasuj/customer-dashboard-link-based-on-condition

1. Run setup upgrade.
2. Clear cache.
3. set permission to var folder.

Answer 2

First You need create block extents class Magento\Framework\View\Element\Html\Link\Current

your block code like

namespace Namespace\Module\Block\View\Element\Html\Link;

use Magento\Customer\Model\Session as CustomerSession;

class Current extends \Magento\Framework\View\Element\Html\Link\Current{

    protected $_customerSession;
    /**
     * Constructor
     *
     * @param \Magento\Framework\View\Element\Template\Context $context
     * @param \Magento\Framework\App\DefaultPathInterface $defaultPath
     * @param array $data
     */
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Framework\App\DefaultPathInterface $defaultPath,
        CustomerSession $CustomerSession,
        array $data = []
    ) {
        parent::__construct($context, $data);
        $this->_defaultPath = $defaultPath;
        $this->_customerSession = $CustomerSession;
    }


    public function _toHtml(){
          // Here you can check the conditions.
          if($this->_customerSession->getCustomer()->getCustomAttribute()){
               return parent::_toHtml();
          }
          return '';
    }  
}
