As mapping a network drive via Net Use requires an elevated command prompt while the user is logged on, this is unfortunately not something that can be done via the deployment module using Net Use.
You may possibly be able to map drives using another method though:
reg add "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\" /v NetDriveMap /t REG_SZ /d "net use X: \\ServerName\ShareName /persistent:yes"
