Hide the whole metabox cmb2

i'm using the famous CMB2 to create custom metaboxes, i want to have one hidden field with default value which i will set myself. i used this hidden field type and its working fine , the thing is the metabox will have this field only, so i ended up with what looks like an empty metabox which may confuse the user. i have read dispaly options but this controls where should the metabox appear, i have it exactly where i want on my posts but i want to set it's visability to be hidden so i do not confuse the user , i thought about using css on this but i want to check if there is a way to achieve this using CMB API
