Yes you can solo-mine NMD.  

Assuming you're using a GPU miner, your config file will include/require the following:

****************************************************************************************************************************************************
rpcuser=somePrivateUserNameThatYouDon'tShare  # the actual rpcuser-name should only be known to you

rpcpassword=SomePrivatePassword  # the actual rpcpassword should only be known to you

server=1
gen=0 # I think you want this value set to zero, you're not using any miner built into the wallet presumably
mining=1 # attempting to solo-mine

port=15716
rpcport=15717 # the port number that NMD clients use

rpcallowip=127.0.0.1

addnode=...
addnode=...
****************************************************************************************************************************************************

Then, using the four things bolded above from the config file, the "batch file" that you'd use for your miner should be:

./ccminer -o http://127.0.0.1:15717 -u somePrivateUserNameThatYouDon'tShare -p SomePrivatePassword -a hmq1725 (any other flags that you use)

Feel free to private-message me if there are any problems (but that should work).  Good luck.

It's also a good practice to encrypt your wallet and ensure that your config file has read-only permissions viewable only by your user account.
