Hello @andymaggs65,
All the my account tabs are in templates/my-account folder. You can override the template by copying it to the yourtheme/user-registration/myaccount/template-file.php
Suppose, you need to edit dashboard,
-> Go to wp-content/plugins/user-registration/templates/dashboard.php
-> Copy this file.
-> Go to wp-content/themes/your-choosen-theme/ and create a folder user-registration and inside this folder create folder myaccount.
-> Paste the copied dashboard.php file here and edit to your requirements. This file will override the plugin’s file.
Basically, the path to be: yourtheme/user-registration/myaccount/dashboard.php
Also, you can left the endpoint empty from User Registration->Settings->Geneal to hide the default tabs.
You may also want to know How to add additional endpoints in my account tab.
Excellent reply and just what I was after, thank you @sanzeeb3
