"..*On a Mac with Apple silicon, the security policy must be set to Full Security, the default setting.."

Plain "Activation Lock for Mac" article refers to M1 exception: at bottom of page.
There, see "Requirements for Activation Lock" section; includes a referral 'blue-link'.
And errors through frustration on my side while attempting keyboard
and mouse hassles, led me to let some errors stand. [Too many typos.]
The earlier link The Littles posted, has this background within.
[the article above "Locking Apple Devices" covers this]
+An adjoined blue link.. to Activation Lock for Mac
• This says:
Note: Mac computers require the Apple T2 Security Chip or Apple silicon
"to be eligible" to use Activation Lock. If an eligible Mac computer is using
user-approved MDM and is upgraded to macOS 10.15 or later, Activation
Lock is disallowed by default and can optionally be allowed. Managing
Activation Lock on installations (not upgrades) of macOS 10.15 or later
requires the device to be supervised. In macOS 11, if a device is super-
vised using a device enrollment (previously known as 'user-approved'
MDM), Activation Lock can’t be managed until the point at which the
device is enrolled into MDM. ~ That means it may be possible for Activa-
tion Lock to already be enabled when the device is enrolled in MDM
and becomes supervised. In that case, it can’t be turned off using MDM
and won’t be disallowed by default, until it is first turned off by the user."
Hopefully you may 'parse all the above' in context.
If your new 16-inch MacBook Pro isn't the latest M1
then you may take a hint of parsley with oregano.
