I’m afraid your question is far to general to answer with any specificity. All I can do, is point you in the general direction.
In order to make Frontend customisations to your theme (i.e. Layout Customisation and Hiding Blocks), you’ll want to read through the Official Magento Documentation for Frontend Development to grasp the basic fundamentals. It’s overwhelming to start with, but you’ll probably have it nailed over the weekend.
If you want to make changes to your Frontend without learning the fundamentals of Frontend Development, you might get a more specific answer to your question by reaching out to the Developers where you purchased your Theme from.
