AFC Channels on GS-BE18000

[VidMan]

I recently got the ASUS GS-BE18000, which fully supports Automated Frequency Coordination (AFC) to increase the transmit power of the 6GHz band based on location. My issue is that the router is saying that the allowed channels do not permit AFC to be turned on for a channel bandwidth greater than 40MHz, which severely restricts the speed benefits of the 6GHz band. Unfortunately, the native interface doesn't let you directly see which channels are allowed based on the location query to the AFC database. Is there any way to ssh into the routers, similar to Ubiquiti APs, to find more detailed information about the AFC status? Manually going through all the channels allows AFC to be enabled for only one 40MHz channel, so either something isn't working correctly or I'm extremely unlucky with neighboring stations.
