I have a X50 v1.32 that doesnt have the firmware for the LAN Port FIx issue mentioned here? https://community.tp-link.com/en/home/forum/topic/675962 Is there a workaround or there is a custom firmware

Is there any way to enable in the Deco X50 the FIX WAN port feature? I already updated it to the most recent version available in the app.. is there any workaround?
