How to enable DHCP option 82 on R770 Unleashed 200.19?

[kelvin]

I'm currently using an R770 with Unleashed firmware 200.19. There's no AC controller on-site, and I don't want to use Ruckus One cloud management; I only want to manage it locally using Unleashed. I need to use the DHCP Option 82 function with the switch to configure different SSIDs. However, I can't find this function setting in the Web GUI. In the CLI, `show wlan all` shows that DHCP Option 82 is present, but it's disabled. I've tried enabling it via command line in the CLI, but I can't find the relevant settings. How can I enable and use DHCP Option 82? I urgently need this function. I would greatly appreciate your help!
