Get the model instance in my form request

I'm using a route model binding. But for the validation, i would like to get the instance of my model ($company) in the form request ($companyRequest)

public function update(CompanyRequest $companyRequest, Company $company) {
    
        $updates = $companyRequest->merge(["active" => $companyRequest->active_check === "on"])
                                                       ->only("name", "phone_number", "address", "active");

        $this->companyRepository->update($updates, $company);

        return back();
 }
