This would need to be custom coded for your site. We give the vendor permission to create and edit products; you’d have to alter the roles and/or create a new role to only allow certain capabilities- and I am not even sure which wp capabilities this would be.
Could you try out the shop manager role (woocommerce role) and see if that meets the needs for your Exhibitor? You might be able to use that role for the permissions you are describing…
