Is there a way to configure how login will look like with enabling SSO using Microsoft.Graph?

I am testing SSO configuration on Acumatica 24R1 with Active Directory using protocol Microsoft.Graph See below web.config > activeDirectory setting we are using:

<activeDirectory
      enabled="true"
      protocol="MicrosoftGraph"
      path="***"
      dc="company.com"
      user="***"
      password="***" />

It works, but with one issue:

All users are created with username that looks like domain.com\username

However, when user is created with such login signs-in into Acumatica, each time they login, in the loginTrace table record is created with Username that has a different format: username@domain.com

Is there a way to control how Login value is created?
Is it possible to make Acumatica to create login as username@domain.com, not as domain.com\username?
