Yes, but it is not a recommended practice by Siemens. It opens up the potential to open the same part, in two sessions, and save the wrong one (been there, done that).
Anyway, the process involves editing the start_nxmanager.bat file. If you search the Siemens "Solution center" for: "How to launch NX without launching Teamcenter and use AW from NX". You should get some info, this is where I started.
Use with caution.
