LEED Boundary for an Existing Multitenant Building

Dear All, We are working on a multi-tenant project in Mexico that wishes to pursue LEED O+M Certification, there are two areas on the ground floor with tenants who do not wish to participate in the certification. If they have independent access to their commercial area, and do not depend on the base building systems, is it possible to leave them out of the certification boundary? We have been doing research and have found the following: "Buildings that are physically connected by programmable space are considered one building for LEED purposes unless they are physically distinct and have distinct identities as separate buildings or if they are a newly constructed addition. If separated, the projects should also have separate air distribution systems and water and energy meters (including thermal energy meters)." I just want to confirm that this is the right path. Thanks in advance!
