Changing NVLOG level fails to start the container, unable to use SRS Rx pipeline

We have rebuilt the container with enable_srs set to 1 in cuphycontroller_P5G_FXN_R750.yaml, and have added a printf statement in cuphyRunSrsRx to check if that part of the code is active. However, the printf statement is never executed. We have tried to activate the debug log. But the container does not start when shm_log_level is set to 6 or 7 in cuPHY/nvlog/config/nvlog_config.yaml, and exits with following error:

Hello,
Foxconn will start to support SRS with release 3.2 that is currently going through testing.

Hi,
When is this update expected?
Is there any other pilot/channel estimation that we can use instead of SRS?
