Is there any way to change the way system is suspended from kde menu

I mean changing the command issued.
I don't know exactly what the default command is, probably systemctl.
/usr/sbin/pm-suspend works better with kernel modules, and I'd like to
use that
It seems that kde uses "systemctl suspend": if I use it from shell,
result is bad as if I suspend from menu.
The defective kernel module cx23885: it doesn't support suspend and resume.
It's a module for a DVB-T PCIe card.
If I'm using kaffeine to watch DVB-T channels, I have to close it before
suspending.
If I leave it opened, kernel module comes up in a broken state.
Closing and opening again kaffeine doesn't help, I have to
-close kaffeine
-rmmod cx23885
-modprobe cx23885
-open kaffeine
This happens suspending with pm-suspend.
Using systemctl, kernel module is broken after every suspend, even if
kaffeine is not running.
My system, if I don't restart Picom, freeze after a resume from suspend.
To fix it I've placed this shell script in
"/usr/lib/systemd/system-sleep/" directory
~$ cat /usr/lib/systemd/system-sleep/00_sleep.sh
#!/bin/sh
################################################################################
# Run from systemd-suspend.service to place under
/usr/lib/systemd/system-sleep/
################################################################################
PATH=/sbin:/usr/sbin:/bin:/usr/bin
case "$1" in
pre)
#code execution BEFORE sleeping/hibernating/suspending
;;
post)
#code execution AFTER resuming
/usr/bin/sleep 5
/usr/bin/touch /home/frank/.config/picom.conf
/usr/bin/sleep 1
;;
esac
exit 0
So I think you've to do the same once you'll have a system that suspend
to RAM properly.
kind regards
