networkmanager and wpasupplicant timers on shutdown?

Hi
I have a Debian Bookworm image for the PineTab2 with plasma-mobile installed.
The problem with this device at the moment is that the bes2600 wifi driver is buggy, and hangs unloading the module (I think that's the problem with it).
The consequence is that it take about six minutes to shutdown/reboot the tablet whilst it waits for networkmanager and wpasupplicant to timeout.
On shutdown you get a call trace from the bes2600 driver.
then: Stopped wpa_supplicant.service - WPA supplicant
then: device enter sleep
then: Job NetworkManager.service/stop running (1min 37s / 3min 3s)
after 3min 3 the timer increases to 4min 33s
then: system-shutdown: waiting for process (NetworkManager)
then: sending SIGKILL to remaining processes
sending SIGKILL to PID 2263 (NetworkManager)
which adds several minutes more

I can't do anything about the bes2600 driver, but, I am wondering if some of these timeouts are configurable and how I could reduce them.

I have also noticed that if I use the pull down menu thing in plasma-mobile (the one that has the shutdown button, airplane mode, etc etc) if I tap on the "WiFi" button to disable WiFi then there is a much shorter delay (two or three seconds) to disable WiFi and then I can shutdown or reboot instantly.

What does that button actually do? and can I do the same thing in a shutdown script?

thanks
