Sorry, Reyee AP doesn't support DHCP Relay option82 function. But Ruijie AP does. The DHCP option 82 is disabled by default on Ruijie AP.
In DHCP Relay scenario, you may run the ip dhcp relay information option 82 command to enable DHCP Option 82.
In DHCP Snooping scenario, you can follow the following commands to enable it:

Ruijie# configure terminal
Ruijie(config)# ip dhcp snooping informationoption //Configuring basic functions of DHCP Snooping
Ruijie(config)# ip dhcp snooping informationoption //Configuring Option82.
Ruijie(config)# end

You can also refer to this guide to configure it on page 458 and page 873:

Appendix: DHCP Option 82, an option for DHCP packets, is also called DHCP Relay Agent Information Option. Option 82 is developed to enhance the security of DHCP servers and improve the strategies of IP address assignment. The option is often configured for the DHCP relay services of a network access device like DHCP Relay and DHCP Snooping. This option is transparent to DHCP clients, and DHCP relay components realize the addition and deduction of the option.
