Yes, you can configure multiple iCloud accounts on your iOS device for the contacts app @_patricia_. Use the CardDAV policy for iOS devices to remotely sync contacts associated with a different Apple ID.
Users can also manually configure different Apple IDs for the Contacts app on the iOS device. To add a new Apple ID, go to Settings app > Contacts > Accounts > Add Account > tap the iCloud option on the device. Now, enter the Apple ID credentials and sign in. The iCloud account associated with the Apple ID will be configured with the Contacts app. You can access data associated with both accounts on the device. Through this method, you can also associate multiple Apple IDs for native apps like Mail, Calendar, Notes, and Reminders.
Cheers!
