Hiding Change my password option on supplier workbench

Hi All,

On the supplier workbench, there is a channel called supplier setup.  we are on premise sourcing system - v10 SP06, and need to hide the option to change password  as this will be done through a vendor portal and not on the system.

However we don't want to hide the channel all together as this will not allow them to maintain their company information...any suggestions?

Any suggestions?

Many thanks
