AutoNotification notification expanded without icon in status bar

Hey there.
I use an app (Franco Kernel Manager) for having a notification with my battery monitor and with this notification I have also an icon on the status bar.
My goal is to have the notification expanded but without the icon.

I've tried different Autonotification/Notification category/Importance settings
- Low: I have no icon but notification is collapsed
- Medium: I have the icon and notification is collapsed
- High: notification is expanded but I have the icon
- Urgent: notification is expanded but I have the icon

Is there a way I can have the notification expanded without the icon?
In that app settings I can only choose if having the notification or not.
Thanks!

 

I forgot: I'm on android 9, custom rom, rooted - xiaomi redmi 4x
