Hi @Pratik Athavale ,
Thanks for using Microsoft Q&A !!
By "change" do you mean "disabling" the email verification ?
If you are using user flows then you can disable the email verification at user signup from Azure portal by going "Page Layout" blade on Azure AD B2C > User Flows > Select policy (For which you want to disable the email verification. You need to change "Requires Verification" to No for "Email Address" user attribute on the page like shown below -
For custom policies, you need set EnforceEmailVerification attribute to false in the TrustFrameworkExtensions.xml file (under ClaimsProviders) to disable the email verification like below and upload the policy file
Please refer to the documentation for details.
