MDATP support for Red Hat Linux >= 8.0

https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/linux-install-manually?view=o365-worldwide

This documentation shows RHEL 8.0 in the examples so should be supported,
and is (probably) not listed in the minimum requirements because it is supported on all minor versions.

Also seemed to work fine in my CentOS 8.2 test machine.

Best bet would be to contact MDE Support.
