Unregistered Windows Hello for Business accounts cannot connect to AzureAD participating PCs via RDP

Question

Case1 is no problem at all, I can make RDP connection.

Case 2 is no RDP connection.

---

Case1　WindowsHello for Business (WHfB) with PIN registered account
　　　　PIN----[ok]--> AADJ PC (AzureAD Joined PC)

Case2 Windows Hell for Business unregistered account

          password ---[NG]---->AADJ PC

          Either the username or password is incorrect. The following message is displayed.
-------------------------------------------------------------------------------------

※　The following is appended to the RDP file.

　　authentication level:i:0

　　enablecredsspsupport:i:0

・Both accounts are already registered on the AADJ PC under “net localgroup ‘Remote desktop users’”.

・WHfB (PIN) is registered at kitting with AutoPilot.

I would like to be able to RDP to AADJPC from a PC that has not been kitted with AutoPilot (account with no PIN registered), but is this possible?
