Hi Jon

Thank you for reaching out to us.

Unfortunately this cannot be achieved using the plugin's builtin features. You can disable the password for he customer panel though and this button will no longer be displayed.

I'll kindly ask you to add a feature suggestion on this page. 

Features are pushed up on our "to-do" list when there are a lot of customers requesting those features, so having your vote as a customer can be beneficial to this feature being developed sooner.

I can explain how to find and copy the selectors you need to use to hide something.

Right-click on the part you wish to hide and inspect the element:

Then, when you hover over the code, that section will be highlighted in the modal. Right-click on the code that highlights the entire div, and go to copy/copy selector:

Paste that selector, and add "display: none !important;", like this for example if you want to hide something

#tab-extras {
display: none !important;
}

So, now Extras field is hidden:

Certain selectors can't be combined, so if it doesn't work when you separate them with a coma, simply add another selector below }

If this doesn't help either, we can recommend these services for customization
