NRF_SO_RAI_NO_DATA AT#XSOCKETOPT=1,50 does not cause RRC release as expected, instead hipower LTE continues another ~20s.
https://github.com/nrfconnect/sdk-nrfxlib/blob/main/nrf_modem/include/nrf_socket.h#L211
Have a look into no RAI release AT dialogue and modem trace.
In case there is UDP packet send just after AT#XSOCKETOPT=1,50, RRC release ocurs immediatelly.
Have a look into RAI release trace and AT dialogue with send.
no RAI release trace and AT dialogue:
