wordpress remove taxonomy metabox
/*
If you are manually registering your custom taxonomy via
register_taxonomy then you can pass in arguments to control where
the metabox appears.
In the example below setting show_ui to false would completely remove
the metabox from the edit screen, the quick edit screen, and the admin
menu. But if you set show_ui to true you can achieve more nuanced control
by then using the show_in_quick_edit and meta_box_cb arguments (setting
the later to false hides the metabox on the CPT edit screen as desired).

register_taxonomy( 'your_custom_taxonomy', array( 'your_custom_post_type' ), $args );
$args = array(
'show_ui' => true,
'show_in_quick_edit' => false,
'meta_box_cb' => false,
);
