I wanted to make changes in _prepareLayout() in block.
Code is as follow:

Block: MagentoCatalogBlockCategoryView

protected function _prepareLayout()

{

    parent::_prepareLayout();



    $this->getLayout()->createBlock(MagentoCatalogBlockBreadcrumbs::class);



    $category = $this->getCurrentCategory();

    if ($category) {

        $title = $category->getMetaTitle();

        if ($title) {

            $this->pageConfig->getTitle()->set($title);

        }

        $description = $category->getMetaDescription();

        if ($description) {

            $this->pageConfig->setDescription($description);

        }

        $keywords = $category->getMetaKeywords();

        if ($keywords) {

            $this->pageConfig->setKeywords($keywords);

        }

        if ($this->_categoryHelper->canUseCanonicalTag()) {

            $this->pageConfig->addRemotePageAsset(

                $category->getUrl(),

                'canonical',

                ['attributes' => ['rel' => 'canonical']]

            );

        }



        $pageMainTitle = $this->getLayout()->getBlock('page.main.title');

        if ($pageMainTitle) {

            $pageMainTitle->setPageTitle($this->getCurrentCategory()->getName());

        }

    }



    return $this;

}

As per above code, I want to make change in below data:

if ($this->_categoryHelper->canUseCanonicalTag()) {

      $this->pageConfig->addRemotePageAsset(

          $category->getUrl(),

          'canonical',

          ['attributes' => ['rel' => 'canonical']]

      );

}

Help me to change the parameter passed to addRemotePageAsset() by overriding block.

you can not override protected methods in Magento 2, only the public method can be overridden using plugin or preference. there is no way to override protected and private method in Magento 2.
