Windows 11 doesn't support RFC 7217 - IPv6 Static Privacy SLAAC

I read online that windows should support (as almost all modern OS) RFC 7217 for IPv6. I have the latest Windows 11 Dev Insider, but it doesn't seem to work.

RFC 7217 states that it should be possible to set a STATIC SLAAC suffix without exposing MAC address.

I have discovered that if I set: Set-NetIPv6Protocol -RandomizeIdentifiers Disabled, I have a static SLAAC suffix address, but it does expose MAC address because it uses the old algorithm where the MAC address is embedded in the last bits (this is not safe nowadays).

If I set Set-NetIPv6Protocol -RandomizeIdentifiers Enabled, I have a random SLAAC suffix address that doesn't expose MAC address but it is not static (it changes when the prefix change).

How can I set a static SLAAC suffix even when prefix changes?
