is it possible to login into on-prem CRM without putting domain name on ADFS login page ?

Hello

We have an On-Prem CRM and ADFS server in our organization, my company has given me the task where the requirement is that user can login into crm without putting domain name on ADFS login page, usually we put the credential like "DomainName\UserName" on ADFS login page. so we need this to be implemented like user could login using Username only on ADFS page, please let me know is this possible ? If Yes then help me to achieve it. 

Thanks
