@Shah Muhammad, Thanks for posting in Q&A. From your description, I know you want to disable lock out screen and set the related policies. But it is not working.
To troubleshoot the issue, please check the following information:
- Are these Intune policies deployed to the devices successfully in Intune portal?
- Is there any GPO with similar setting applied to these devices?
If the policies show successful and there's no related GPOs applied, I suggest open case to do detailed log analysis to see if more information can be found:
