Disable azure fields when creating a virtual machine with terraform

Hello community!!!
I am new to terraform implementation and I have some specific questions, I am currently trying to create a VM with terraform, but in the disks section I need to disable some fields like: enable ultra disk support, OS ephemeral disk and Use managed disks.

The problem is that in the official documentation I do not see that there is a field to disable it, if someone has the codes I would appreciate if you could share them with me, or if by default terraform does not allow to disable these fields, I would appreciate if you could confirm me the no action.
