Stopping Synchronization of incoming data from UCMDB to Smax with SCCM discoveries

Hello,

SCCM integration is available on UCMDB. With SCCM integration, devices coming from UCMDB automatically create device records in smax. I don't want to limit smax recording of data from other discoveries. Only update the device information of the devices coming from SCCM in SMAX, but do not add new devices. How can I perform this operation?
