Is there any equivalent of HTML.RAW in Blazor?

To render the RAW HTML, wrap the HTML content using MarkupString value, which is rendered into DOM and HTML or SVG.

 @page "/"
  
  
 @((MarkupString)myMarkup)
  
 @code {
     private string myMarkup =
         "<p class='markup'>This is a <em>markup string</em>.</p>";
 } 

Refer to the Blazor documentation for more information.
