Serialize children based on ability

I have the following model :

class Member
   belongs_to :enterprise

class Enterprise
   has_many :members
   has_many :enterprise_projects
   has_many :projects, through: :enterprise_projects

class Project
   has_many :enterprise_projects
   has_many :projects, through: :enterprise_projects

class EnterpriseProject
   belongs_to :project
   belongs_to :enterprise

I also have the following permissions defined in ability.rb

class Ability
  include CanCan::Ability
  
   def initialize(user)
     can :manage, Enterprise, members: { id: user.id }
     can :manage, Project, enterprises: { members: { id: user.id } }
   end

Combined with the following ProjectsController :

class ProjectsController < ApiController
   load_resource :enterprise, through: :current_member, singleton: true
   load_resource except: :create
   authorize_resource

   def index
      render json: @projects
   end

   def create
      project = Project.create(create_params)
      @enterprise.enterprise_projects.create!(project: project)
      project.save!
      render json: project
   end

Which allows me to restrict restrict the management of projects from a member to only projects associated to its enterprise. (and a project created by a member will be attached to its enterprise). However, if a member fetches a project, the enterprises attribute of the serialized object comprises all the enterprises attached to the project, but I would like it to be only the list of enterprises the member has access to (in this case it would be only one since member belongs to one company). How can this be achieved ?
