To hide Comments in page source code you need to Minify your HTML Code.
To enable minify you can use CloudFlare or any plugin that allows you to minify HTML.

how can i minify html code? i dont use cache. so i need to use cache?

You can also manually delete that section inside the comments from the main functions file inside the /theme/includes/td_booster/ folder.

You can use Autoptimize plugin
under Autoptimize settings

HTML Options
Optimize HTML Code? chech (enable) this option
