Blazor MSAL AD B2C integrate multiple user flows (profile edit, change email, change phone number)

I have an AD B2C tenant with the user flows SignupSignin, ProfileEdit, ChangeEmail, ChangePassword userflows. I am trying to integrate the user flows in the Blazor application.

The Blazor client application has the appsettings.json file has option to specify only one user flow

{
  "AzureAdB2C": {
    "Authority": "https://tenant.b2clogin.com/tenant.onmicrosoft.com/B2C_1A_signupsignin",
    "ClientId": "*************",
    "ValidateAuthority": true
  }
}

Is there any way to call the other user flows from the Blazor application ProfileEdit, ChangeEmail, ChangePassword?

Is there any way to change the Authority dynamically at runtime on clicking the menu profile edit, change email and change password to navigate to the b2c userflows?
