I noticed that the previous bmcweb WIP for ComponentIntegrity was auto-abandoned [2] and there does not appear to be an active effort to implement these routes upstream.

I wrote this patch in about 25 minutes while sitting in a meeting
discussing how difficult the SPDM/ComponentIntegrity feature would be
to build.  If you want to take it over, feel free.  If you have
updates, please send them to Gerrit, and I will be happy to review.  I
don't know anyone who has continued the component integrity work on
Redfish, so the engineering work is likely yours if you want to take
it on.
