Portsecurity on Nexus C3064PQ

I get:

SW1(config)# feature port-security ^ % Invalid command at '^' marker. SW1(config)#

we want to limit this thing to 1 MAC / Port but I have no clue right now what I'm missing, this is what the online cisco documentation for nexus 300 said.

Software BIOS: version 4.0.0 NXOS: version 7.0(3)I4(6) BIOS compile time: 12/05/2016 NXOS image file is: bootflash:///nxos.7.0.3.I4.6_compact_N3064.bin NXOS compile time: 3/9/2017 22:00:00 [03/10/2017 07:05:18]

someone got an idea for me? I cannot find anything on google that leads clearly somewhere...

cisco stated on their website this feature is included with no license needed.....
