How can i hide the product_type on dokan edit

hello everyone, I need to hide the part where it says type of product and also where it says discount price because I do not want my sellers can change it or see I have tried to edit product single but there is no way that if I change it there breaks the form and disappears all that are attributes and shipping I have been able to hide other things like inventory but I do not see the way to hide or hide that part because if I modify it breaks everything someone knows how I can do I would be grateful greetings and thank you
