Hi @kuldeep-in, 
Could you please provide the exact location how to disable DPM enabled option as i was not able to locate it in pipeline settings or Databricks settings.
Thank you

if you add these settings in the pipeline JSON, the issue should get fixed:
"pipelines.setMigrationHints" = "true"
"pipelines.enableDPMForExistingPipeline" = "true"
I tried it on my side, and now it no longer throws the materialization error.
