It required support in dogtag which was added in 10.5.0.
This is only easily configurable during installation because
it will set ca.signing.defaultSigningAlgorithm to the
selected algorithm in CS.cfg
The certificate profiles will generally by default set
default.params.signingAlg=- which means use the CA default.
So while an existing installation will technically allow
SHA384withRSA it will require profile changes and/or
changing the defaultSigningAlgorithm in CS.cfg and
restarting (completely untested). And that won't affect
already issued-certificates.
