Hi Rich Peliel. Private previews are generally closed and by invite only based on a few factors. The best bet for participation in some private previews is to join and engage in the Microsoft Custom Connection Program: https://techcommunity.microsoft.com/t5/windows-it-pro-blog/join-the-windows-customer-connection-program/ba-p/3473775. Note that we (Intune) generally don't do public preview anymore.
