Unwanted notifications on cellular connection status changes

[wrc08 6]

Hello,
I hope my post is in the right place here. I am not a professional but love the F (x) tecPro1.
I have a problem and hope someone in the forum can help me.
My F (X) tecPro1 is paired with my SmartWatch (Garmin Fenix5). I have activated call diversion in my F (X) tecPro1. Every time the status of the F (X) tecPro1 cellular connection changes, I get a notification on the F (X) tecPro1. This is also passed on to my smartwatch. It's very annoying. It cannot be switched off because in "function settings > Apps & notifications > Show all apps > Show system processes > Telephone services > Notifications" the deactivation for call diversion is not possible. The option is checked, but I cannot switch it off. It has a gray background. (just as: status of the SIM card, SMS, mailbox messages and WLAN telephony)

Can someone tell me how to turn these options off, or how can I activate the buttons so that I can remove the tick?

I switched everything else off, but nothing helps.

Many thanks for the help.

I took the liberty to split this into a new thread. Feel free to give it a better title, (I just tried to summarize)

And unfortunately I have not got an answer.

Perhaps it can be deactivated inside the Gamin Connect App?

Thank you for thinking along and for looking for a solution.

I've already tried to deactivate the notifications directly in the app.

The app (Connect) offers this option, but only for apps that the user has installed.

The telephone services are a system app and therefore they are not even listed in Connect.
