Yes, I believe so.
It appears that connecting MitID to an application (also called an SP) requires utilizing an approved broker. A broker is essentially an OIDC connector.

We haven’t tested this, but based on reviewing Signicat’s OIDC documentation, the process seems fairly straightforward. They are one of the MitID brokers.
