Exchange 2019 for Multiple Tree Domains

I'm in the process of setting up exchange servers within a multiple tree domain environment. example:

Parent domain: philly.com (has exchange setup)

Tree domain 1: eagles.nfl (trying to install/configure new exchange server so it will only see AD users in this domain)

Tree domain 2: sixers.BB (setup another new exchange server as above)

I was able to prepare /prepare schema, /prepareAD, /preparealldomains. I performed the exchange server install for the eagles.nfl domain, but when I launch ecp I can see all the mailboxes in the forest. What commands do I need to run to setup Exchange in the tree domain to only see the recipients in its respective domain and not the forest? hopefully I explained this well.

Thanks

    Thats not possible. Exchange orgs are per AD forest so you cant prevent the ability to see all the domains as admin.

    Users segmentation in the GAL is possible:
