Dear developers!
Could you please consider possibility to change default kernel config, used in release versions of Armbian, so it enable to forcefully unload of kernel modules ( to do this config option CONFIG_MODULE_FORCE_UNLOAD needs to be enabled). This is seldom but regular needs for me and I beleive for many others in case of external hardware malfunctions, for example.
Previosly I have used selfcompiled version of Armbian 5.15 where named option was enabled and anything was fine. Now I have upgraded to Armbian 21.08.1 Buster by installing release version of it because it seems dramatically more complicated to compile by myself.
Now in case of freezes of my bluetooth adapter which connects to gsm phone to send some alerts, the only way to restore its functioning is to do system restart, while uloading an reloading (rmmod -f btusb; moprobe btusb) bluetooth driver was enough.
