Manually Configure Server alt-svc Header?


I'm new to OLS and am keen on trying out its QUIC and HTTP3 support.
I'm wondering though, if I can advertise only a subset of the available versions on my server.

The HTTP3 check tool shows that I'm compliant on Q43, Q46, Q50, as well as draft versions 23 and 24 of HTTP3.
My test client (Chrome Canary) seems to prefer Q43 -- even when I run with --quic-version=h3-24, for example.

The OLS GUI doesn't seem to offer anything more precise than just enabling or disabling QUIC altogether.
Is there any way I'd be able to manually edit my alt-svcs to force the client to a QUIC/HTTP3 version of my choosing?
