SSO Configuration options for mandate SSO

[masayuky]

Hi, I'm using SAML with other IdP and I noticed there are 2 methods to sign in the zabbix I build, login with username and password locally or SSO.
And I would like to restrict the use of username and password login for certain user accounts and force them to use SSO, is there such an option?

I wish there is the option that is to mandate SSO for some selected members.

Thanks.
