While you can’t directly have two separate properties for the same domain in GA4, you can achieve your desired outcome of having one view with all data and another excluding internal traffic.

Create a single data stream for your domain.
Within this data stream, set up two views:
View 1 (All Data): This view remains unfiltered, showing all traffic data.

View 2 (Internal Traffic Excluded): Create a filter in this view to exclude internal traffic. You can achieve this by filtering based on IP addresses, hostname, user agent, or other criteria that identify your internal users.
