Activation lock enabled on device which is in 30 days DEP provisional period

Hi Apple community,

I am writing this regarding device based activation lock can enable on device which is in 30 days DEP provisional period. Within the DEP provisional period, I can remove the remote management on my device. So the device is considered to use as my personal device ,not organization owned. Since MDM device based activation lock can enable during this provisional period, The device no longer be referred to use as my personal device also . what is the use of that 30 days? Kindly educate us on this case to whether this an intended options or a bug.

Thanks in Advance
