Disable ability for user to change password in Azure AD

I really hope Microsoft would listen to their customers and implement this feature. Our organization have a lot of dumb people who keep forgetting their password, after they changed it themselves to their own preference. It was too much of a bother to us IT staffs to reset their password to them. It will be a huge help if we can simply disallow them from changing password. This way, we can simply them to look up their password in the secured pdf we once sent them.
