Hi @zmansuri,
As far as I am aware you cannot configure this in the settings of the out of the box Approval action like Start and wait for an Approval. Unfortunately, the title will appear by default in the body of the e-mail 😞
As a workaround you could use the Create an Approval action. This action will output the Teams Adaptive Card json.
You could manipulate that json with a replace function and post your it in your own Send an Email (v2) action.
Below is an example
1. Use a Create an approval. Make sure you disable notifications

2. Use a Send an email. Switch to code view and and HTML code (including an expression which uses an adaptiveCard with a replace function. That function looks for the Title and replaces it by an empty string value).
<script type="application/adaptivecard+json">@{replace(outputs('Create_an_approval')?['body/adaptiveCard'], outputs('Create_an_approval')?['body/title'], '')}</script>

Below is a test example e-mail without the Title in the body.
