Hide unlicensed users from searches across M365 apps

Hello, 

Is it possible to hide unlicensed users from searches across the M365 suite? We have ex-employees that are still active in the user admin as unlicensed. We can't delete them because their mailbox has been converted to shared, so that multiple employees can access the content. 

I found this, but not sure it applies to other apps. https://techcommunity.microsoft.com/t5/microsoft-teams/hide-generic-unlicensed-users-from-ms-teams/m-p/334749#M25848

If MS is going to keep unlicensed users in searches, it seems like a reasonable request

Thanks, 

Mike
