As a reseller and I wanted to hide SSO logins (both Login to cPanel button in sidebar and also the Quick shortcuts in client area product details).
I searched this forum for a solution, but found only partial answers, so here I am with a good solution (which worked for me, WHMCS 6.x)
Remove Quick Shortcuts
You need FileManager / FTP for this. Copy the tpl file located at /modules/servers/cpanel/templates/overview.tpl and paste it in your template folder at the following path – /templates/yourtemplatename/modules/servers/cpanel/overview.tpl (here your template name will probably be five or six and you may need to create folders modules/servers/cpanel, because they are not present by default).
Now, edit the line # 137 to look like this (just add && 0)
{if $systemStatus == 'Active' && 0}
Basically, you have created a override template file which overrides the default functionality and removes the Quick Shortcuts etc in the client area.

Remove Login to cPanel in Sidebar
This bit is fairly easy, no need to edit any tpl files etc. Just create an empty file at /includes/hooks folder (name it expresstech_cpanel_removal.php) and paste the following content. Done!
