Unfortunately, no, there's no flag to turn off this.
But, from your experiments, if you applied that patch,
("rtw88: disable TX-AMSDU on 2.4G band") connect to AP on 2.4G, and still crash
the Comcast AP, then it looks like it's not TX-AMSDU to be blamed.
Assume the return value you mentioned is max_rc_amsdu_len, if you always
return 1, it will just disable all of the AMSDU process.
You can try it, and to see if sending AMSDU will crash the router or not.
