Eval cannot be permanently activated, it only supports time based Eval channel. Upgrading to non-Eval works only for Servers IIRC.
I just tested it, LTSC 2021 Eval seems to be having activation issues. Activation worked fine in 2016, 2019, and 2024 LTSC Eval.
xinso claims that it is possible https://forums.mydigitallife.net/th...prise-n-ltsc-2021.84509/page-211#post-1852696
What xinso claimed, useless if you did not test\fulfill it. (It had been discussed between zhanglin and xinso at the old Reconstruction thread.)

Hi guys. Today i do a fresh installation of Windows 10 IOT LTSC 2021 from an old version 2019 and i notice the license is still be "Actived". My question is: does it remain or some bad day it will ask me for activating. Thank you guys.
