Uninstall SP3 for SSIS taht is on the same box as Database Engine

Hi,

I have applied sp3 to the existing SQL Server 2012 sp1 and have issues with SSIS packages that are similar to this link. Now I have to roll back the change just on SSIS instance. In this case database engine and SSIS instance share the same box and while uninstalling the update I am getting this error

Is there a way to un install just the sp3 for the SSIS instance as we want to keep the database engine on SP3

Thanks
