You are best off putting in a blanking plate (only £4 delivered) for two good reasons....
Whilst many of the earlier engines cannot detect if the EGR is blanked (the newer ones use a MAP sensor to check the air flow), the earlier ones do not ( and so will not even raise a warning light when blanked).
However, if you fiddle with the electronics, the system may detect tampering and give a warning light or go into limp mode.
Once you have your EGR and DPF delete, which is done by physically removing the DPF, and mapping out the use (but leaving it physically in place) of the EGR, the EGR may still be leaking air into the manifold (epsecially if it is older), so many people fit a blanking place at this point anyway.
