Hi @Vinod S Patil 

In this requirement, We need to know the importance of maintaining the OOTB functionality as much as possible to ensure future compatibility with updates and to reduce the maintenance overhead of custom solutions. While ServiceNow does allow for extensive customization to meet specific business needs, it encourages thorough testing and evaluation of any customizations to prevent negative impacts on system performance, maintainability, and upgradability.

Note: Please Mark this Helpful and Accepted Solution. If this Helps you to understand. This will help both the community and me..
- Keep Learning ‌‌
Thanks & Regards
