Remove Sign In option on the some page

[Rupaali]

Hi,

 

I am collaborating with another agency to print some of my work. I am using the agency widget on some of my pages.

 

In order simplify the process all buyer needs to purchase as guest in my website. I was able to disable the hook for the "sign in" option on right topmost corner of the page. But pages created by prestashop such as product-list, product, contact, blog I am not able to disable/hide it. For e.g I was able to disable sign in option on the page http://rupaali.com/en/content/25-paintings but not on the http://rupaali.com/en/oil-pastel/33-ramesh.html

 

 

Also during checkout I do not want to show the account creation option.

 

 

Please let me know how to handle this situation.
