[ironic] HTTPS Provisioning

Good day, I hope this is the right way to ask. Is it possible to use IPXE HTTPS or UEFI HTTPS Network boot with Openstack Ironic, because most of the communication or completely should be encrypted. Or how do you have to configure this. Unfortunately, I have not yet found any instructions in the documentation. Of course, it is also necessary to import the certificates or install IPXE on the client side. Perhaps I have overlooked something and would like some clarification. Best regards Michael
