Hi Bezzo,
You can easily hide the submit button with CSS.
This code below lets you enqueue a CSS file for the settings page:
add_action( 'admin_enqueue_scripts', function() {
$screen = get_current_screen();
if ( 'your-screen-id' == $screen->id ) {
wp_enqueue_style( 'your-file', 'http://url-to-your.css' );
}
} );
To get the screen ID of the settings page, you can use the Inspector plugin. The screen ID is shown in the "Help" tab, like this:

In your CSS file, you can simply enter this:
.wrap .submit { display: none; }
If the process above is complicated, you can use a "quick and dirty" tip below:
When you register a meta box for the settings page, add a custom_html field like this:
$meta_boxes[] = [
// Other fields
[
'type' => 'custom_html',
'std' => '<style>.wrap .submit { display: none; }</style>',
]
];
It will output the <style> to the page and hide the submit button.
.
