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']]
