Learn how to turn on Find My so you can locate a lost Apple device or an item — such as your paired AirPods, Apple Watch, or a personal item with an AirTag attached.
I had the same issue. Both find My Mac and two factor were enabled but activation lock status was disabled. Only one thing was disabled that needed enabling and it was the option called Find my network . Looks like this has to enabled as well?
I have this issue with my new 16” M1 MBP. I am really, really sure that 2FA is on, Find My is on (including FMN), and that the boot security is set to “full.” Despite that, activation lock shows Disabled.
It's the damnest thing. I spent the entire evening last night toggling FindMy, singing into and out of iCloud, even booting into boot options and toggling full/reduced security. Nothing changed the AL status. I went to bed convinced I was going to have to take it to a genius bar.
This morning, it's enabled. Literally nothing happened between then and now except time.
