NUX: need to disable the Submit button in Manager Evaluation step

Content

We are planning to turn on Responsive pages in Performance module in October.  I have a requirement to hide the Submit button when a performance document in the Manager Evaluation step, but keep it enabled for workers when the PD in the Self Eval step. 

The following EL works just fine in Performance, but it disables the Continue button in Benefits since this is a shared component.  

#{(pageFlowScope.pTaskCode == 'WSEVAL' and pageFlowScope.pReadOnly != true) or ((pageFlowScope.pTaskCode == 'MGREVAL' && pageFlowScope.pSectionTypeCode =='REG') or (pageFlowScope.pTaskCode == 'MGREVAL' && pageFlowScope.pSectionTypeCode =='GOAL')) }

What do I need to change in the logic to ensure the EL is applied only in Performance and does not mess up other modules (Benefits, Succession, etc.)? This is a “must”, we will not be able to go live if this requirement is not met.
