Hello,
The plugin doesn’t have any settings, we aim to make it work well for the majority of users by default, but there are always case-by-case customizations you’ll want to make for your client.
We actually just released an update which shows the Yoast SEO Metabox (when editing posts/pages). So now only the Settings menu is hidden. If this accomplishes what you need, just upgrade to 1.3.1 and that should fix your issue ??
If you would like to customize the permissions for your client further, you could check out our Pro version [https://tylerdigital.com/products/webmaster-user-role/] which adds a Settings panel to better customize the admin area for your client.
Here are some screenshots of the settings pages in the Pro version:
