Yes it's possible. Under <SEPM installation folder>\ASA\win32 there is the dbisqlc.exe tool with which you can launch SQL queries against the embedded database. User ID is dba, password is your initial admin password of the SEPM console. (Bad luck if you don't have it anymore!)
Then connect with an ODBC data source and choose SymantecEndpointSecurityDSN.
If this tool is too ascetic for you, there are some free SQL GUI tools in the net which can be used as well. Some years ago I tried Anysql and it worked fine.
