for example, by use apt install xxx I installed some deb package on my ubuntu xenial system. 

grub2-common                       2.02~beta2-9ubuntu1.14

How do I modify this version so that dpkg -s xxx( or just any command output from dpkg utility) will return my customized version number?

here would be an example of modification result from output of dpkg -l | grep grub2-common

grub2-common                       2.02~unicorn<3-9ubuntu1.999

I managed to discover that by modify status file under /var/lib/dpkg directory (requires root permission), one would be able to get modified package version which reflect in dpkg utility output.
