Remove SAP Screen Persona, Logout

Hi,

We have integrated SAP Screen Persona in Portal. USing shotlink have assigned couple of tcodes to test users.

When we access it from Portal we see  SAP Screen Persona title and logout option for flavours assigned with rendering access.

Screenshot attached Persona_Top_Level.png.

Can somebody suggest how can we remove the top level from flavor assigned in Portal.

Thanks

Sushma
