How to delete LAGG/LACP configuration?

We've been using a 6-port 10GbE LACP LAGG between our FreeNAS NAS and the XS728T in our post yltra hi-def production/editing studio. We handle mostly 2K/4K/6K film production

Anyway, most of the time it has worked well. But, there is occasional severe bandwidth variances and dropoffs that aren't acceptable in film production. So, we've decided to go back to a simple setup od 6 invidually configured NIC ports, each with it's own small sub-domain(10.0.1.x, 10.0.2.x, 10.0.3.x, etc). We'll assign a 2-3 of workstations to each port/sub-domain and see if that stabilizes bandwidth.

Unfortunately, I cannot figure out how to delete the existing LAG,. It's 2AM, so maybe it's just fatigue

Any help greatly appreciated
