Hello martinoland1,
Thanks for taking the time to reach out here in Apple support communities. Based on your post it sounds like you want a way to manage how contacts and incoming calls are displayed on your iPhone 11. Is that correct? We'll be happy to help.
Just to confirm, are you inquiring about your call history using the Phone app? If so, there wouldn't be a way to change how incoming and outgoing calls are displayed, but you can submit feedback about the Phone app using the feedback link below.
As far as your contacts you can change how your contacts are displayed. This can be done by managing the default account being used with your contacts, or by toggling "Contacts' off for the email accounts configured on the iPhone. If your content with the default account being used to save your contacts, managing the email accounts being used with contacts may help.
The article below can help. Take a look under "Turn Contacts on or off for an account."
Manage and delete contacts on your iPhone, iPad, or iPod touch
