Can Invalid database E-business Suite objects be ignored if the module/product is not used

Hi,
Can Invalid database E-business Suite objects be ignored if the module/product  is not used

For example those packages are invalid

OKE_AGREEMENT_PVT                                  PACKAGE BODY        INVALID
OKE_DELIVERABLE_UTILS_PKG                          PACKAGE BODY        INVALID
OKE_DELIVERABLE_UTILS_PUB                          PACKAGE BODY        INVALID

but I don't use the OKE module.

Can I ignore those invalids ?

Regards,
Eric.
