@Richa Kumari , After researching, i find that locked enrollment works a little differently, at first, on devices not originally purchased through Apple Business Manager but later added to be a part of automated device enrollment: users on these devices will see the remove management button in the Settings app for the first 30 days after activating their device. After that provisional period, the option will be hidden.

Could you confirm if our devices are originally purchased through Apple Business Manager? If not, then we can see the remove management button in the Settings app for the first 30 days after activating their device.
Hope it can help.
