Template override,disable title and top menu

Hello,

I use the hako template and I have to do some overrides because of the layout.
If I try to make the overides, there is no override file in mytemplate/html/com_easyblog/...
Joomla says "making override file" but there is no.
How can I make overrides for hako?

I also don't need the title, the description and the top blog menu (home, categories, tags, author ...) but I am not able to find the switches to disable these areas.

Thanks & regards
