Need help - I want deactivate video call - how to?

So I descibed it in the topic: I want deactivate video call the video call option - how to?
Thanks for help

I don’t believe you can (certainly not easily as I haven’t seen any settings to do this).

Why do you want to disable? Is it causing you an issue?

Maybe you could contact your mobile operator and ask them to deactivate it.

Thanks for reply,
accidently I tapped videocall - thats not part of my flatrate so I have to pay extra for this without need. All my contacts are not this tech-freaks using the latest shit, merely because it´s possible …
I look for a solution, Thanks!
