R7800 jump back to 5ghz DFS Channel

[NetgearR7800]

Hi, i 'm still on stock fitmware 1.0.3.92 and i always wanna use Channel 100 in 5ghz and i get kicked very often because of an aiport in my town. Then i have to set Channel 100 again because there is no autochannel function for 5ghz in the UI. Is there a possibility to jump back after the 30 Minutes in the Voxel Firmware oder is there a autochannel function for 5ghz?
Thanks a lot for any information.

I used to have the R7800, but if you are using DFS channels, then this can happen, can you just use channel 36? for 5ghz band?

With Channel 36 i only get 50mbit of my 100mbit downspeed. 10mbit up is no problem. I tested all channels. Best and most stable is 100 with 40mhz bandwidth without HT160 with MIMO. I have a MediaTek Wi-Fi 6E MT7922 160MHz Wireless LAN Card. Tried the Microsoft and proprietary driver. With 2.4ghz i only also get only 50mbit down.
So the nicest would be to come back to 100 if i got moved to an other channel.
