By MEM, here, I assume you mean ConfigMgr.
Also, just to clarify, ConfigMgr doesn't manage MBAM, it manages BitLocker. It does this using an agent which is more or less the same agent as MBAM uses and is (effectively) part of the ConfigMgr agent.
As for determining whether or not a BitLocker RK has been escrowed to the ConfigMgr DB, there are built-in reports for this: https://www.prajwaldesai.com/sccm-bitlocker-reports-in-configmgr-console/. You can also create your own reports or queries in the console. I believe there are folks that have made console extensions as well.
