I don't think that is true, at least not in my experiments with a combination
of the T470s and the Lenovo Thunderbolt 3 dock. The DP links were created
independently of security level.
There are a few people reporting issues with the TB16 and the XPS13 and
external displays inside RH. Some report it as a regression when upgrading to
F28. The current working hypothesis is that it might be related to MST. Lyude
has been doing some where in that area lately.</pre>
