In macOS 15, the new Private MAC address settings is enabled by default, and there is a new settings in Profile to disable it, BUT it's only for a spacified SSID.

If you need a global setting to disable the Private MAC for all existed and new SSID, try to create a new policy to run this command:

sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist PrivateMACAddressModeSystemSetting -int 1

It will not disable the Private MAC Address immediately, but it will work after forgot the network or reboot the computer.

If I remember correctly, it's not just for a specific SSID. I think that SSID's network must be deployed with a Configuration Profile.

@AJPinto You are correct, in Jamf Pro 11.9.1 the "Disable MAC Address Randomization (macOS 15 or later)" option is part of the Network payload in a Configuration Profile and only applies to the SSID being configured in that Network payload.

Anybody have issues with this working? I saw Jamf has the option now in WiFi configuration profile, but in our network anything with Private Mac Address is blocked. So I think when users upgrade to sequoia they dont get the chance to grab that setting before they are blocked.

Here is a blog post by @brunerd which describes a mechanism for disabling MAC address randomization that can be deployed to Macs running macOS Sonoma so when they are upgraded to macOS Sequoia they won't start with randomization enabled:
