Hi @sweb ,
We are a bit unclear about your Requirement,
However, you can try out, customizing the profile page with the help of the localized content page of the Profile Web page and the Profile Web Form for the Form that is used on the profile Web page,
Step 1: Navigate to the Profile web page in the Portal Management app and look for the localized Content,

Step 2: change the HTML in the Content Section

Step 3: Now look for the Profile Web Form in make.powerapps.com,
Portal/Power Pages use this form on the Profile Web Page,

Step 4: To hide the Marketing Options on the profile web page,
Look for the Profile/ShowMarketingOptionsPanel in the site settings and set the value as false to hide the Marketing Options,

If this doesn’t meet your requirement, Please elaborate your requirement.
Thanks!
