EL Expression works but is there any other/better way to write it

Hi ,

We are using EL Expression which works but is there any better way to write it (pls see point 3) ,can any one please share the feedback or experience  on this 

Requirement -  Hide something (e.g. My client groups - whole ) which is shared across roles and also will be shared potentially when a new role is going to be created but should not be visible to a role X only at the moment

1)  #{!securityContext.userInRole['X']}   This doesn't work in total as person can have X role but also Y ,Z role so access should be there for him as we want person only having X role should not see, but this hides it moment X is there.
