How to add custom OAuth2 provider to MS Outlook?

Hello

I would like to connect MS Outllook with my own Oauth2 server (for example Keycloak). 
Is there any option to force Outlook to use custom authorization endpoint for my domain?

I read about autodiscover.xml mechanism but there is nothing about OAuth2. 
For example Mozilla Thunderbird allow to modify OauthProvider structures by dev console or special addon (https://thunderbird.topicbox.com/groups/addons/Tc85dff9ce12063c6-Mca4319b1e41dfa4b426e22fc). Is there any chance to achieve the same effect on MS Outlook? 

p.s.

according tohttp:// https://www.rfc-editor.org/rfc/rfc8414.html#section-3 does ms outlook should follow mydomain/.well-known/oauth-authorization-server to obtain info about endpoints. scopes etc for mydomain or i'm wrong?

Thank You for any hint.
