Do you want to change the user login url which starts with https://login.microsoft.com.....? in AAD B2C login. If so its not available.
Check the below FAQ.
Can I use my own URLs on my sign-up and sign-in pages that are served by Azure AD B2C? For instance, can I change the URL from login.microsoftonline.com to login.contoso.com?
Not currently. This feature is on our roadmap. Also note that verifying your domain in the Domains tab of your tenant on the Azure classic portal will not do this.

What is the status of this feature? We would love to use Azure AD B2C but there are concerns that a redirect to a site other than our own will lead to a higher abandon rate. We would like to supply a Vanity URL that Microsoft uses to host the login page.

Currently this feature is not available . We checked with engineering internally and we are unable to provide a timeline for the same as well for now due to technical complexities . Please keep checking the uservoice page Customer-owned domains - User Voice . We apologize for the same however this is going to take more time and currently does not have any specific workaround .
