Possible to unlock LTE Band 12 on G930V?

I know in the past on older Samsung devices (S5, etc) there was a way to unlock more LTE bands on the Qualcomm based devices.. I have a Verizon S7 and I'd like to upgrade this unit to a Note 7. I want to use the S7 on my AT&T SIM card. AT&T uses band 17 and band 12 primarily but the G930v doesn't support the band out of the box.

Is it possible to unlock the other LTE bands on the G930v?

Thanks in advance
