Sprint note 4 SIM unlock topic

Hi all, I have a Sprint note 4 and love it. However I also have a Go Phone sim from work and want to use this Note 4 on that network.
I have looked all over the web for days and can't find the answer - can the Sprint Note 4 be SIM unlocked for domestic USA use for AT&T?
I know that the radios are there for every network (much like a Google Nexus phone has all radios)...

Thanks.
