For anyone wanting this—I got this working by adding the fields myself to configuration.py beneath SSO Configuration:

# SSO Configuration
... OKTA
... GOOGLE

SOCIAL_AUTH_AZUREAD_OAUTH2_KEY=environ.get('SOCIAL_AUTH_AZUREAD_OAUTH2_KEY', '')
SOCIAL_AUTH_AZUREAD_OAUTH2_SECRET=_read_secret('azuread_oauth2_secret', environ.get('SOCIAL_AUTH_AZUREAD_OAUTH2_SECRET', ''))
SOCIAL_AUTH_AZUREAD_OAUTH2_TENANT_ID=environ.get('SOCIAL_AUTH_AZUREAD_OAUTH2_TENANT_ID', '')

From this i was redirected correctly to the EntraID app and got auth successfully

Followed the documentation from Netbox for Azure side of the setup:
