It looks like authselect doesn't support that.
While authconfig tried to be a super-multi-tool that knew how to
configure all the things, I think it got to a point where it was too
difficult to maintain (keeping track of which options were required,
conflicted with each other, etc.). So authselect instead ships a
pre-set group of config files that have been tested, with some options
in them.
Right now, the password algorithm is always sha512. I think that could
be turned into what authselect calls a "feature", but I'm not sure
(that'd be a good request for the project, using their project page at
https://github.com/authselect/authselect). It looks like features might
support only enable/disable, not custom string values.
The "officially correct" way to do that today seems to be to create a
custom profile (which can be based on an existing profile), change the
values, then apply the custom profile. This seems like a lot to just
set the algorithm, but I'm guessing that at this point, there aren't
many requests to do that (so it isn't a well-supported thing to change).
It looks like something like this might do it:
authselect create-profile sha256 --base-on=sssd
sed -i 's/sha512/sha256/g' /etc/authselect/custom/sha256/*
authselect select custom/sha256
