We have an existing TRUNK link, set for "switchport mode trunk" on e1/49 and e1/50 (2 main uplinks). They are acutally working right now. However, we are getting a ton of broadcast packets on the uplinks because we host VM's which require vlans to be added to the TOR's, so when we attempt to prune or filter the vlan allowed list to reduce the broadcasts down, the commands are not present.

switchport mode trunk
logging event port link-status
logging event port trunk-status
channel-group 1 mode active
Then when attempting to configure anything related to "switchport", it doesnt recognize the command: Basically, it wont even take "switchport" and then enter.
fake-x34-1-61# conf t
Enter configuration commands, one per line. End with CNTL/Z.
fake-x34-1-61(config)# int e1/50
% Incomplete command at '^' marker.
fake-x34-1-61(config-if)# switchport ?
host Set port host
monitor Configures an interface as span-destination
So, how is this possible if I'm already a working trunk interface currently? Also, there isnt a feature I found that turns pruning/filtering on per say.
What is the recommended way to do this pruning if its not supported? This link says it should work fine (and I would think it would too).

Since the port is in a port-channel, you will need to make the change in the port-channel interface, in this case port-channel 1. This is a nice feature they introduced with NX-OS to prevent port-channel port mismatches.
On classic IOS, it allows you to prune VLANs on individual ports in a port-channel, but it brings down the port channel because the individual interface configurations don't match.
