Yes, when using MS LSA APIs (CyberSafe implementation) and retrieving tickets we don’t need to set AllowTgtSessionKey registry as MS LSA APIs are able to get the tgt and service tickets for you and the code don’t need to know the session keys.
We even tested with Credential Guard (some months back) running and MS LSA APIs were able to get tickets without any issues on Windows.
Can I know why you want get the TGT session key when using MS LSA APIs?
I haven’t use MS LSA library for Linux and so I am not very sure on this.

It used to be the case that the MSLSA cache would work reasonably well
without TGT keys available.
Namely, if you retrieved a ticket the cache would ask the LSA to get the
ticket for you,.
Does this no longer work?
If this does work, does it meet your needs?
If not, what functionality are you missing?
