B2C custom policies - Remove email change step in azure b2c - azure-ad-b2c

Question

I used this documentation to split email verification and signup.
I would like to remove the third page in the email verification flow as you can see in the image from the page above. (It's the one with the 'Change email' button).
Is there a way to prevent email verification for a second time? Do I need to remove an orchestration to acheave it?
A question was asked in this link, I tried the same solution but it only hides the change email button, but not associated elements.
This is my Technical profile for emailVerification :
<TechnicalProfile Id="EmailVerification">
<DisplayName>Initiate Email Address Verification For Local Account</DisplayName>
<Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.SelfAssertedAttributeProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
<Metadata>
<Item Key="ContentDefinitionReferenceId">api.localaccountsignup</Item>
<Item Key="language.button_continue">Continue</Item>
</Metadata>
<CryptographicKeys>
<Key Id="issuer_secret" StorageReferenceId="B2C_1A_TokenSigningKeyContainer" />
</CryptographicKeys>
<IncludeInSso>false</IncludeInSso>
<InputClaims>
<InputClaim ClaimTypeReferenceId="email" />
</InputClaims>
<OutputClaims>
<OutputClaim ClaimTypeReferenceId="email" PartnerClaimType="Verified.Email" Required="true" />
</OutputClaims>
</TechnicalProfile>
And this is my userjourney for combined signup and signin flow :

Thanks for help.

Answer 1

As per the answers you found, you must hide that button with CSS.

Answer 2

The solution suggested by #Jas Suri in this link solved my problem.
You can use JavaScript mutator function. Use it to detect that the Continue button has changed property (become enabled), and then trigger a function to hide the Change button and perform a click event on the Continue button.
