By default the footprint report is checked into Dimensions in the original project, which may cause the footprint to be deployed. If you do not want to deploy the footprint, use a different project to collect the footprint reports. The filename generated is globally unique so one project can collect footprint reports for all builds.
Use the variable DM_FOOTPRINT_CHECKIN_PROJECT in dm.cfg to specify where the footprint is checked in, where:
*CURRENT: checks the footprint into the current project.
*NONE: checks the footprint into $GENERIC.
Default value: the variable contains the name of the project in the format PRODUCT:PROJECT.
