Hi BilalAliAhmad,
Unfortunately, we do not have an official sample support LWM2M Client for nRF52840, only one for nRF9160: LwM2M Client — nRF Connect SDK 2.3.0 documentation (nordicsemi.com).
You can refer to some discussion on RE: LwM2M client does not connect with Leshan demo server on nRF52840 DK
and test with the public Leshan server first.
Best regards,
Charlie
