Hi Toan,
We have designed our theme this way. Yes you need to create a page to display blog full content display template. And then go to dashboard -> setting -> reading -> front page display (choose static page ) and select the blog page.
Then this will display the front page full content display.
If you don’t want featured image to be displayed in single page then it needs code customisation. So you need to create a child theme before making any changes on it.
Thank you!
