@karthik palani , In general, many of the device settings that you can manage with Endpoint security policies (security policies) are also available through other policy types in Intune. These other policy types include device configuration policy and security baselines. Because settings can be managed through several different policy types or by multiple instances of the same policy type, be prepared to identify and resolve policy conflicts for devices that don't adhere to the configurations you expect.
We can use Troubleshooting + support and check Per-setting status to find the conflict policy and then remove it. Here is a link with more details for the reference:

Hope it can help.
