I moved your post to the appropriate English section.
This is impossible for every SIM on Telefonica/o2 network, VoLTE/WiFi Call does not have a switch on the network-side like you can’t opt of 2G or 3G calls on this side. May I know your special reason, maybe there is a different solution.
With good smartphones you can switch off WLAN calling, VoLTE and RCS. These are pure device settings and make less sense on the provider side or via SIM.

Why not? However, it is not a meaningful question to a consumer forum, but should be requested as a business letter from o2.
