@Jay_mahapatra - If you have already done with macOS Reset, then its totally up to you on deciding which enrolment process your organisation would like to follow. As a Best Practise, it is recommended to enroll using Automated Device Enrollment because this prevent the users from removing the MDM profile from System Settings and also we have more control on the devices enrolled via ADE.
When it comes to your question of removing the Mac Computer entry from Jamf, its is recommended to configure the "Re-enrolment" Settings from Jamf Pro Settings > Global to ensure you have enable the following and you will no longer require to remove the Jamf Computer entry while re-enrolling the device to Jamf Pro. Jamf will compare the device Hardware UUID / Serial number and overwrite entries as new computer with same Computer / Mobile Device ID, but the follow items will be cleared as you have set them to clear during re-enrollment. Let me know if this is helpful.
1. Clear user and location information on mobile devices and computers
2. Clear user and location history information on mobile devices and computers
3. Clear policy logs on computers
4. Clear extension attribute values on computers and mobile devices
5. Clear Management History On Mobile Devices And Computers
