When using the Pulumi-Terraform bridge, is there a way to have it /not/ set a particular field of a resource? Like, not set the field at all, not pass anything to the Terraform provider.

I’m investigating an issue with the Proxmox provider (<https://github.com/Matchlighter/pulumi-proxmoxve>). There seems to be an upstream issue with the Terraform provider it’s using (<https://github.com/Telmate/terraform-provider-proxmox>), in which the QemuVM resource’s field `preprovision` has ConflictsWith set on several other fields, such as `os_type`.

When using Terraform, you can ignore this and simply not set `preprovision` at all, so there’s no conflict. But in the Pulumi provider, it seems to be setting this field regardless. Even not specifying `preprovision` at all, or setting it to false or undefined causes it to conflict with the other fields. This effectively means that in the Pulumi provider, you can’t set `osType` or `sshUser` at all.

So as a fix for the issue, the Pulumi-Terraform bridge should not send this field when it’s not set. Is that possible?
