Login as local-user despite default redirect to SSO/OIDC provider

I’ve set up OpenID login and it works. I’ve configured it to automatically redirect to SSO when login is required. For testing purposes, I also wanted to create a local user. Is it possible to circumvent the auto-redirect to OpenID Connect on a case-by-base basis, so that I can log in as the normal user? WikiJS for instance allows one to do this by appending ?all=1 to the URL.
